Somali officials have confirmed a U.S. airstrike killed the intelligence chief of the militant group al-Shabab. The Pentagon had announced the strike, but did not identify the target. Somali officials say the leader, Abdishakur Tahlil, was killed along with two other senior al-Shabab members. An earlier U.S. strike in September killed the leader of al-Shabab, sparking a deadly revenge attack on an African Union base in the Somali capital Mogadishu last week.
