Syria live updates: Israel to remain in Syria beyond buffer zone

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.
