The United States has blocked the United Nations Security Council from issuing a statement condemning the airstrike on a migrant detention center in Libya which left 44 people dead, according to a report in Germany. Deutsche Welle reports that British representations circulated a statement that condemned the air strike and called for a ceasefire when the council met Wednesday. However, the U.S. reportedly prevented the 15-member Security Council from issuing a statement. The U.S. State Department had earlier condemned the air strike, but didn't go as far as to call for a ceasefire. The air strike hit a detention center in Tripoli on Wednesday. Libya's UN-backed government in Tripoli blamed the attack on the insurgent Libyan National Army.
