Exclusive from Reuters:

In March of this year an attack on a Somali migrant boat killed 42 and injured 34. There were over 140 people on board.

At the time, no one claimed responsibility for the attack, but now United Nations investigators are placing the blame on the Saudi-led coalition.

“This civilian vessel was almost certainly attacked using a 7.62 mm caliber weapon from an armed utility helicopter,” the investigators, who monitor sanctions in Yemen, wrote in a 185-page report to the U.N. Security Council on Monday.

“The Saudi Arabia led coalition forces are the only parties to the conflict that have the capability to operate armed utility helicopters in the area,” the report said. It said the helicopter was likely operating from a naval vessel.
