DUBAI (Reuters) - Twitter suspended an account linked to Iran’s Supreme Leader on Friday, hours after it carried the image of a golfer resembling former President Donald Trump apparently being targeted by a drone alongside a vow to avenge the killing of a top Iranian general in a U.S. drone attack. The post, on a Persian-language account linked to Khamenei’s website, had carried the text of remarks by Ayatollah Ali Khamenei in December, in which he said “Revenge is certain”. That speech renewed a vow of vengeance ahead of the first anniversary of the killing of top military commander General Qassem Soleimani in the attack in Iraq.
