Tehran has condemned U.S. air strikes on Iran-linked forces in Syria that reportedly killed 19 people, which Washington said it carried out following a deadly drone attack on U.S. forces. The Iranian Foreign Ministry late on March 25 condemned "the belligerent and terrorist attack of the American army on civilian targets" in the eastern Syrian region of Deir el-Zor. Washington said it launched the retaliatory raids after a U.S. contractor was killed -- and another contractor and five military personnel wounded -- by a drone "of Iranian origin" that struck a U.S.-led coalition base in Syria.
