The Pentagon says the United States carried out multiple airstrikes in Somalia Sunday, following a deadly truck bombing in the capital Mogadishu that killed nearly 80 civilians. No group has taken responsibility for Saturday’s deadly bombing, which also wounded nearly 150 people. Officials have blamed the attack on the militant group al-Shabab. It was the worst attack in two years in Somalia. One day after the bombing, the Pentagon said it killed at least four people in airstrikes targeting al-Shabab. The United States is carrying out an increasing number of airstrikes in Somalia — killing at least 800 people since April 2017.
