Top US hostage negotiator in Lebanon, official says
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.
