The Taliban has claimed responsibility for a missing U.S.soldier in Afghanistan.

A Taliban's website claimed militants have captured and arrested a "drunken U.S. soldier." The soldier has not been seen since walking off a U.S. base five days ago.

The terrorist organization has yet to provide any proof.

Meanwhile, seven U.S. troops died in Afghanistan on Monday. Two of those military personnel were killed in the southern region of the country where thousands of U.S. Marines are pushing forward with the largest military offensive against the Taliban since 2001.
