Turkish President Recep Tayyip Erdogan accused the United States and the United Kingdom of using excessive force in retaliatory strikes against the Iran-backed Houthis in Yemen, in an apparent show of a strategic rift between the NATO allies.

“They are eager to turn the Red Sea into a bloodbath,” Erdogan said Friday. “Yemen, namely the Houthis, say they have given and will continue to give the necessary response to them, be they the U.S. or U.K., in the region by using all their power.”
