ABOARD USS HARRY S. TRUMAN, Ramadan 3, 1437, Jun 8, 2016, SPA -- The U.S. military will have two aircraft carriers in the Mediterranean Sea this month ahead of a NATO summit in Warsaw as Washington seeks to balance Russian military activities and accelerate its fight against Islamic State militants, Reuters reported. The USS Harry S. Truman aircraft carrier will hand off to the USS Dwight D. Eisenhower when it arrives en route to the Gulf, allowing the Truman to head back to the United States after an extended eight-month deployment, Navy officials on board the Truman said. The United States European Command later issued a statement confirming that the Dwight D. Eisenhower Carrier Strike Group had entered the Mediterranean Sea on Wednesday "in support of U.S. national security interests in Europe". The move coincides with NATO military exercises across eastern Europe and Turkey that may raise tensions with Russia. U.S. officials say Russia is operating warships and submarines in the Mediterranean and plans its own exercises in coming weeks. -- SPA 21:08 LOCAL TIME 18:08 GMT www.spa.gov.sa/w
