Iran seeks to avert US military action with talks in Ankara

Turkey hosts urgent mediation as Trump's threats mount and Tehran weighs painful compromises to avoid conflict

Iran's foreign minister, Abbas Araghchi, will travel to Ankara for talks aimed at preventing a US attack, as Turkish diplomats seek to convince Tehran it must offer concessions over its nuclear programme if it is to avert a potentially devastating conflict.

Turkey's president, Recep Tayyip Erdoan, proposed a video conference between Donald Trump and his Iranian counterpart, Masoud Pezeshkian - the kind of high-wire diplomacy that may appeal to the US leader, but would be anathema to circumspect Iranian diplomats. No formal direct talks have been held between the two countries for a decade.
