"This is not a violation of the nuclear agreement," media quoted White House spokesman Josh Earnest as saying on yesterday, referring to "Joint Comprehensive Plan of Action" -- the nuclear deal implementation mechanism.

The P5+1 group, namely the US, Britain, France, China, Russia and Germany, reached the comprehensive nuclear deal with Iran on July 14, 2015. The accord would provide sanctions relief for Iran in exchange for limits on its controversial nuclear programme.

Earnest, however, said an investigation was underway to review the incident and determine whether it should be raised at the UN Security Council.

Earlier yesterday, Iran test-fired several ballistic missiles in the ongoing military drills attended by the senior commanders of the Islamic Revolution Guards Corps (IRGC).

The missile drill was aimed "to show Iran's deterrent power and also its ability to confront any threat against the (Islamic) Revolution, the state and the sovereignty of the country", the IRGC's official website said.

Earnest stressed that if it was determined that Iran ballistic missiles tests were in violation of UN Security Council resolutions, Tehran could face "some consequences".
