“This is the latest of many provocative and hostile actions by Iran against vessels operating in international waters. The United States reserves the right to defend our personnel, facilities, and interests,” Trump said.
“The drone was immediately destroyed,” Trump said. He gave no more details.
The Pentagon said in a statement that the USS Boxer, an amphibious assault ship, had taken “defensive action” against a drone, but did not mention if the aircraft was Iranian.
Tensions in the Gulf region are high, with fears that the United States and Iran could stumble into war.
The United States has blamed Iran for a series of attacks since mid-May on shipping around the Strait of Hormuz, the world’s most important oil artery. Tehran rejects the allegations.
Earlier on Thursday, the United States demanded Iran immediately release a vessel it seized in the Gulf, and a U.S. military commander in the region said the United States would work “aggressively” to ensure free passage of vessels through the vital waterway.
