The United Arab Emirates said on Sunday that tensions between the United States and Iran in the Gulf can only be addressed politically and priority should be de-escalation and dialogue. "Crisis long in the making requires collective attention; primarily to de-escalate and to find political solutions through dialogue and negotiations," UAE Minister of State for Foreign Affairs Anwar Gargash said in a Twitter post. Tensions remain high after US President Donald Trump said on Friday he aborted a military strike to retaliate for Irans downing of an unmanned US drone because it could have killed 150 people. Iran has said it would respond firmly to any threat against it and warned on Sunday of the risks of a military confrontation. Trump, in return, has warned that he will impose further sanctions on Iran from Monday.
