Iran warns against complying with US sanctions as Gulf attacks reported

Iran's Fars news agency later cited an unidentified source as saying that vessel had been "sailing under the US flag and belonged to the United States".Also on Sunday, Kuwait said drones had entered its airspace and that the military had "dealt with them".Hours later, the UAE said its air defences had intercepted two drones coming from Iran.The US has a significant military presence across the Gulf, with bases in Qatar, Bahrain, Kuwait, the UAE, Saudi Arabia and Oman.In Friday's incidents, the US said Iran had launched missiles, drones and small boats against three of its warships, in what it called an "unprovoked attack".Iran's top military command, meanwhile, alleged the US had targeted an Iranian oil tanker and another vessel approaching the Strait of Hormuz and carried out "aerial attacks" on several coastal areas.Tehran has leveraged its effective control over the waterway - through which around a fifth of the world's oil and natural gas usually flows - in the war, which began with US and Israeli strikes on 28 February.Both the US and Iran have attempted to implement rival blockades in the strait, as negotiations on ending the conflict have so far failed to reach a resolution.
