The Pentagon says it launched an airstrike in Afghanistan Saturday targeting the Taliban's overall leader, Mullah Akhtar Mansur, who was killed, according to Afghan and Taliban officials. 

A U.S. official said Saturday, however, that Mansur was "likely killed" in the airstrike. Afghan intelligence confirmed Sunday to ABC News that Mansur was killed. And Senior Taliban commander Mullah Abdul Rauf also told The Associated Press Sunday that Mansur had been killed in the airstrike.
