President Donald Trump is prepared to offer Iran sanctions relief and release frozen Iranian funds in exchange for concrete steps on Tehran's nuclear programme before agreeing to a final deal, according to a US official.
The potential economic concession has emerged as Qatari and Pakistani mediators try to break a renewed diplomatic impasse between Washington and Tehran. A US official described the indirect discussions as 'positive and constructive', but stressed that there would be no final agreement unless the nuclear dispute was addressed.
