Iran’s top diplomat said on Sunday that only “prudence and foresight” could alleviate tensions between his country and Britain after Tehran’s seizure of a British-flagged oil tanker. “Having failed to lure @realDonaldTrump into War of the Century, and fearing collapse of his #B_Team, @AmbJohnBolton is turning his venom against the UK in hopes of dragging it into a quagmire,” Mohammad Javad Zarif said on Twitter. “Only prudence and foresight can thwart such ploys.” Britain has called Iran’s capture of the Stena Impero in the Strait of Hormuz on Friday a “hostile act”. Tehran for weeks has vowed to retaliate for the seizure of its Grace 1 oil tanker by British forces for violating European Union sanctions on Syria.
