Rebel forces in Syria captured the capital Damascus and toppled the regime of President Bashar Assad in a lightning-quick advance across the country.
Meanwhile, the ceasefire in Lebanon is holding despite ongoing Israeli airstrikes on Hezbollah targets, which Israeli officials say are responses to ceasefire violations by the Iranian-backed militant group. The Israel Defense Forces continues its intense airstrike and ground campaigns in Gaza.
Tensions also remain high between Israel and Iran after tit-for-tat long-range strikes in recent months and threats of further military action from both sides.
The U.K.-based Syrian Observatory for Human Rights watchdog said Tuesday that Israel has conducted around 310 airstrikes across Syria since the fall of former President Bashar Assad’s regime on Sunday.
The group — which documents war crimes and human rights abuses related to the Syrian Civil War and has generally been described as pro-opposition and anti-Assad — said the targets included Syrian airports, aircraft, radars, air defense systems, scientific institutions and weapons and ammunition depots.
SOHR said Israeli strikes have been reported all across the country, from Deir Ez Zor in the east to the coastal province of Latakia in the west. Israeli strikes have reportedly hit targets in major cities including the capital Damascus, Aleppo, Hama, Homs and Daraa, SOHR said.
Israeli Foreign Minister Gideon Saar confirmed Monday that Israeli forces “attacked strategic weapons arrays, residual chemical weapons capabilities, missiles and long-range rockets” inside Syria to prevent them from falling into the hands of “extremist elements.”
The Syrian Civil Defence, also known as the White Helmets, said it had concluded its search for detainees within Sednaya Prison on Monday after failing to uncover any “unopened or hidden areas” within the facility.
The prison previously held thousands of people detained by the former regime of ousted President Bashar al-Assad. Families of the missing and survivors believed that some detainees might have been unable to leave over the past two days, potentially due to being held in tightly sealed and secured areas, those close to the situation told the White Helmets, prompting the search.
“Specialized teams conducted a thorough search of all sections, facilities, basements, courtyards, and surrounding areas of the prison,” the White Helmets said in a statement. “These operations were carried out with the assistance of individuals familiar with the prison and its layout. However, no evidence of undiscovered secret cells or basements was found.”
The statement also called on international organizations and local authorities to support the efforts of the Syrian Civil Defence in uncovering the fate of the detainees and returning them to their loved ones.
“We share the profound disappointment of the families of the thousands who remain missing and whose fates remain unknown,” the statement continued. “We stand in solidarity with the victims’ families, fully understanding their anguish and their longing for answers about their loved ones.”

Secretary of State Antony Blinken said senior officials from his department are “fanning out through the region as we speak” to work with their counterparts on how the U.S. can “help support the Syrian people as they decide their own path for the future.”
“We have a strong interest in preventing the reemergence of ISIS, given the death and destruction that it has wrought for so long,” he said during remarks at an unrelated event on Monday.
Blinken noted that ISIS would seek to exploit the moment, and that U.S. strikes on ISIS sites over the weekend demonstrate that the U.S. is “determined not to let that happen.”
“We have a clear interest in doing what we can to avoid the fragmentation of Syria, mass migrations from Syria and, of course, the export of terrorism and extremism,” he said. “The region and the world have a responsibility to support the Syrian people as they begin to rebuild their country and charge a new direction.”
Blinken also said that with every party they engage with, he and other U.S. officials will continue to seek information on American freelance journalist and Marine Corps veteran Austin Tice, who went missing while covering the civil war in August 2012, “so that we can find him and bring him home to his family and loved ones.”

The special presidential envoy for hostage affairs is in Lebanon as the Biden administration tries to capitalize on the fall of the Assad regime to uncover information on the whereabouts of missing American freelance journalist and Marine Corps veteran Austin Tice, according to a U.S. official.
The envoy, Roger Carstens, was in Doha last week but traveled to Beirut when the Assad regime fell, the official said. The Biden administration is working through multiple partners in the Middle East — most notably Lebanon and Turkey — to track people coming out of Syrian jails.
However, U.S. officials say they still have very little intelligence on Tice’s whereabouts and can’t say with certainty that he is even in Syria.
Tice went missing while covering the civil war in August 2012.

The Syria Civil Defence, aka the White Helmets, announced Monday it is offering a $3,000 reward for any direct information that will lead them to Assad’s “secret” Syrian prisons.
The organization addressed former security officers and those working in the security branches for help in accessing the prisons, adding they will maintain the confidentiality of sources.
Turkish President Erdogan said Monday that Turkey is opening the border gate with Syria for the return of migrants.
Erdogan said they are opening the Yayladağı border gate to crossings “in order to prevent congestion and ease traffic.”
There were long lines at the border earlier awaiting this decision.
Germany and Austria have paused asylum for Syrian refugees after Assad’s regime was toppled.
The German interior minister called the situation in Syria “very confusing” and that due to the unclear situation, they have “imposed a freeze on decisions for asylum procedures that are still ongoing until the situation is clearer.”
Nearly 1 million Syrian refugees live in Germany.
Austria’s interior minister has also instructed the ministry to “prepare an orderly repatriation and deportation program to Syria.”
Nearly 100,000 Syrian refugees live in Austria.

Debra and Marc Tice — the parents of Austin Tice, a U.S. journalist and prisoner in Syria since 2012 — released a statement urging “anyone who can do so to please assist Austin so he can safely return home to our family” following the collapse of Bashar Assad’s regime.
“We are watching the events unfold in Syria and seeing families reunited with their loved ones after years of separation,” said a statement released via the Press Freedom Center at the National Press Club.
“We know this is possible for our family, too,” they added. “Austin Tice is alive, in Syria, and it’s time for him to come home. We are eagerly anticipating seeing Austin walk free.”
Tice went missing while reporting in Syria in 2012. President Joe Biden said Sunday his return remains possible, though acknowledged that “we have no direct evidence” of his status. “Assad should be held accountable,” Biden added.

White House National Security Adviser Jake Sullivan told “Good Morning America” on Monday that “it is good for the United States and the world that a murderous dictator whose family has ruled Syria with an iron fist for half a century is gone.”
Sullivan did, however, echo President Joe Biden’s warning that there is real risk that “terrorists, jihadists and other people who do not have the United States best interests at heart…could take advantage of this.”
“We are vigilant about that,” Sullivan said in an interview with ABC News’ George Stephanopoulos. “We are taking action to deal with that, and we’re prepared to work with anyone in Syria who wants a stable, inclusive, democratic future for that country.
Sullivan said that the U.S.’ top priority is “to protect the United States of America from the resurgence of a terror threat” emanating from Syria.

“That means holding ISIS down,” he added. “Don’t let them take advantage of this. Then there is the priority of making sure that our friends in the region are secure and stable — Israel, Jordan, Iraq, Lebanon — that these countries do not suffer from any kind of violent spillover effects from what’s happening in Syria.”

Russian President Vladimir Putin will grant political asylum to toppled Syrian President Bashar Assad, Kremlin spokesperson Dmitry Peskov told reporters on Monday.
“Of course, such decisions cannot be made without the head of state,” Peskov said, as quoted by the Russian news agency Interfax. “This is his decision,”
“We have nothing to tell you about Mr. Assad’s whereabouts right now,” Peskov said, adding there was no official meeting between Putin and Assad planned.
