Iran and the United States are sliding rapidly towards military conflict as hopes fade for a diplomatic solution to their standoff over Tehran’s nuclear programme, officials on both sides and diplomats across the Gulf and Europe say, BBC reported. 

Iran’s Gulf neighbours and its enemy Israel now consider a conflict to be more likely than a settlement, these sources say, with Washington building up one of its biggest military deployments in the region since the invasion of Iraq in 2003.

Israel's government believes Tehran and Washington are at an impasse and is making preparations for possible joint military action with the United States, though no decision has been made yet on whether to carry out such an operation, said a source familiar with the planning, according to BBC.
