A truck bomb killed at least 20 people in Somalia’s capital on Saturday and left several people trapped in the rubble of a hotel. At least 15 people were injured in the blast, which locals described as the most powerful explosion to hit Mogadishu in years. Authorities said the blast appeared to target a hotel on a busy road near the country’s foreign ministry. The bombing came just two days after the head of the U.S. Africa Command visited the city to meet with Somalia’s president. There was no immediate claim of responsibility but the extremist group al-Shabab has been know to target the area. Police said the death toll is expected to rise.
