Iran is ready for a full prisoner exchange with the United States, Iranian government spokesman Ali Rabiei says, adding that Washington has yet to respond to Iran's call for a prisoner swap.
"We have announced that we are ready without any preconditions to exchange all prisoners and we are prepared to discuss this issue but the Americans have not responded yet," Rabiei told the news site Khabaronline on May 10.
"We are worried about the safety and health of Iranians in jail.... We hold America responsible for Iranians' safety amid the new coronavirus outbreak," Rabiei added.
"Washington is aware of our readiness and we think there is no need for a third country to mediate between Tehran and Washington for the prisoner exchange," Rabiei was quoted as saying.
