The United States joined in a coalition attack against Libya’s air defense system Saturday using Tomahawk cruise missiles and aerial jamming, according to the Pentagon.

White House officials and Secretary of State Hillary Clinton said ground troops won’t be sent by the U.S., and the Pentagon reiterated that during a Saturday briefing.

The goal of Saturday’s operation was to establish a no-fly zone. As many as 25 U.S., Canadian and Italian vessels participated in the attack, Bloomberg reported, adding that the armada boasts three Navy submarines: the USS Florida, USS Scranton and USS Providence.

During the Pentagon briefing, it was stressed that arab and UN nations were on board with this attack to stop Libya’s leadership from attacking its own people.
