Iran's Foreign Ministry released an official statement on Sunday announcing the termination of arms restriction imposed on the country.
It said that the definitive and unconditional termination of arms restrictions and travel bans requires no new resolution, state news agency IRNA reported.
"In one of the JCPOA’s innovations, the definitive and unconditional termination of arms restrictions and travel bans requires no new resolution, nor does it require any statement or any other measure by the Security Council," the statement read."
"The lifting of arms restrictions and the travel ban were designed to be automatic with no other action required," it added.
The embargo on the sale of conventional arms to Iran was due to start expiring progressively from Sunday, October 18, under the terms of the UN resolution.
In 2015, Iran struck a nuclear deal with the US, China, Britain, France, Germany and Russia.
However, US President Donald Trump withdrew his country from the deal in 2018 and has unilaterally begun reimposing sanctions on Iran.
But Washington suffered a setback in August when it failed to win support from the United Nations Security Council to indefinitely extend the arms embargo, according to AFP.
Washington has said it has decided to unilaterally reinstate virtually all of the UN sanctions on Iran lifted under the accord.
