U.S. deploys search and rescue helicopters to Iraq in ISIS fight

The Pentagon is placing search and rescue helicopters in northern Iraq in an effort to reduce the time and distance needed to reached downed pilots, CBS News national security correspondent David Martin has learned.

The move comes after the Islamic State of Iraq and Syria (ISIS) released a video Tuesday purporting to show a Jordanian fighter pilot being burned alive.

Lt. Muath al-Kaseasbeh was captured by ISIS in December after his F-16 crashed in Syria. The video also threatened other purported Jordanian pilots by name.

Two U.S. officials said Wednesday that the United Arab Emirates, an important part of the U.S.-led coalition fighting ISIS, stopped flying combat missions over Syria late last year after al-Kaseasbeh was captured.

According to the New York Times, which first reported the decision, the UAE chose to suspend its participation in the airstrikes out of concern for its pilots' safety.

U.S. officials have said that every effort was made to recover the Jordanian pilot, in coordination with the Jordanian military. They have said that as soon as al-Kaseasbeh's plane went down, an intensive airborne search was initiated, but it was not possible to locate the pilot before he was picked up by ISIS fighters.

On Wednesday morning, Jordan's air force carried out more bombing raids against ISIS, CBS News correspondent CharlieD'Agata reported. Jordanian officials will also decide whether Jordan may send in ground troops in the fight against the terror group.
