Hostage envoy Roger Carstens traveled to Syria Friday, making the first known U.S. in-person contact with the caretaker government, and seeking help in finding missing American Austin Tice.

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

The mother of Austin Tice, who was taken captive in Syria in 2012, voiced hope that upheaval in the country will lead to freedom for her son.
