Last week, Iranian President Hassan Rouhani said Tehran would give the remaining signatories to the 2015 nuclear deal 60 more days to fulfill their obligations before proceeding to the third stage of reducing Iran's commitments under the landmark treaty.

Axar.az reports citing foreign media that Iran "will revert" to its commitments under the Joint Comprehensive Plan of Action (JCPOA) nuclear deal immediately if its European signatories implement their part of the agreement, regardless of US participation, Foreign Minister Mohammad Javad Zarif has announced.

Warning about the dangers he said was posed by the Trump administration's "unpredictable" policies, Zarif noted that Iran may act "unpredictably" in response.

"Mutual unpredictability will lead to chaos. President Trump cannot expect to be unpredictable and expect others to be predictable," the foreign minister said.

"Gulf Arabs cannot achieve security (in the region) by spending billions of dollars on purchasing Western weapons...No amount of foreign military presence (in the Gulf) can prevent insecurity," he said.
