Iran reportedly test-fired ballistic missiles as part of a military exercise Tuesday. The tests come two months after the United States imposed sanctions on Iran in January over its ballistic missile test conducted in October last year.

Iran's Revolutionary Guards test-fired ballistic missiles from silos to "show Iran's deterrent power and also the Islamic Republic's ability to confront any threat against the (Islamic) Revolution, the state and the sovereignty of the country," according to the IRNAnews agency. 

In October 2015, Iran tested the missile named Emad, which was its first precision-guided weapon. Iran was at the time banned by the United Nations Security Council Resolution 1929 from conducting ballistic missile tests that can enhance its capability of deploying nuclear warheads. 

"Iran's ballistic missile program poses a significant threat to regional and global security, and it will continue to be subject to international sanctions," the U.S. Department of the Treasury had said in January. 

Decades-old international sanctions on Iran were lifted in January after the latter complied with the provisions of the nuclear deal under the Joint Comprehensive Plan of Action reached last July. 

While the UN Security Resolution 1929 expired following the lifting of sanctions in January, a new resolution was effected that called upon Iran to refrain from undertaking tests of missiles "designed to" deliver nuclear weapons, according to Reuters.
