AP: In a stepped-up response to Iranian backing of Shiite rebels in Yemen, the Navy aircraft carrier USS Theodore Roosevelt is steaming toward the waters off Yemen to beef up security and join other American ships that are prepared to intercept any Iranian vessels carrying weapons to the Houthi rebels.

The deployment comes after a U.N. Security Council resolution approved last week imposed an arms embargo on leaders of the Iranian-backed Shiite Houthi rebels. The resolution passed in a 14-0 vote with Russia abstaining.

Navy officials said Monday that the Roosevelt was moving through the Arabian Sea. A massive ship that carries F/A-18 fighter jets, the Roosevelt is seen more of a deterrent and show of force in the region.
