The US official, who did not want to be named, said Trump did not like the proposal. Earlier this morning, President Trump discussed the proposal with his top national security advisers.

Iranian sources said on Monday that the proposal called for the suspension of talks on the country's nuclear program until the war is over. At the same time, it also mentioned resolving disputes over shipping in the Gulf. However, Washington has said that it wants a solution to the nuclear issue from the beginning.

Meanwhile, a source in the mediating country Pakistan said that the work of reducing the distance between the two countries has not stopped yet. However, hopes of reviving the peace process have faded.
