The US and Iran are closer to an agreement to end the war and Washington and Tehran have stepped up negotiations to end the military conflict. Iran has expressed its willingness to discuss the issues of its nuclear program, which it previously excluded from negotiations, reports Bloomberg. Qatar acts as a mediator between the countries. Through him, Iran submitted proposals on the nuclear program to the United States, but Tehran insists that negotiations are possible only after Washington fulfills a number of conditions. Iran demands the lifting of US sanctions, the release of frozen assets and the lifting of the naval blockade. The United States, in turn, insists on including the nuclear program on the agenda of the negotiations. Despite the increase in diplomatic contacts, serious disagreements remain between the parties. A final agreement has not yet been reached.
