Taliban Claims Responsibility for Attack That Left Four US Soldiers Dead

Set to begin talks with the U.S.

The Taliban has claimed responsibility for an attack that killed four U.S. troops in Afghanistan, hours after the U.S. announced it was opening formal talks with the insurgent group.

A Taliban spokesman said the group fired two rockets into the Bagram air base on Tuesday.

Earlier, the U.S. said direct negotiations with the Taliban will begin Thursday in Doha, the capital of the Persian Gulf country of Qatar,  in a push to establish a framework for ending more than a decade of war in Afghanistan.
