Bryan Stern, founder of Grey Bull Rescue, says evidence points to a safe return of American journalist and former U.S. Marine Austin Tice, along with other prisoners detained by the brutal Assad regime in Syria.

Prime Minister Benjamin Netanyahu told Tice's mother his country won't conduct airstrikes near a secret prison outside Damascus.

We should ask the militants who toppled Bashar al-Assad in Syria what became of missing U.S. reporter Austin Tice and why

Nongovernmental workers and journalists have scoured prisons for clues about his fate in the absence of an official American presence in the country.

There are no credible hints of his whereabouts, but also no clear evidence that he is dead, a U.S. official said.

US group Hostage Aid Worldwide says it believes journalist Austin Tice, who went missing in Syria in 2012, is still alive, but didn’t offer concrete information on his whereabouts.

Hostage Aid Worldwide said Tuesday that American journalist Austin Tice, who has been held in Syria for 12 years, is alive. "We know that as a fact." Syria has publicly denied that it was holding him.
