U.S. group Hostage Aid Worldwide said Tuesday that it believes journalist Austin Tice, who went missing in Syria in 2012, is still alive, though it did not offer concrete information on his whereabouts.

"We have data that Austin is alive till January 2024, but the president of the US said in August that he is alive, and we are sure that he is alive today," Hostage Aid Worldwide's Nizar Zakka said.
