“It was decided that should the international community be forced to act in Syria, the most responsible and sustainable response would be limited missile strikes,” the official said on condition of anonymity on Tuesday following a meeting held in the Jordanian capital, Amman.
The military leaders led by Chairman of US Joint Chiefs of Staff General Martin Dempsey agreed to prepare for the strike as early as this week, the official added.
Meanwhile, the British Prime Minister David Cameron’s spokesman said UK armed forces are devising contingency plans for military action against the Arab country over the alleged use of chemical weapons.
The UK has been reportedly sending warplanes and military transporters to its airbase in Cyprus, situated near Syria.
US defense officials also say several navy destroyers have been deployed to the Eastern Mediterranean to be used against Syria upon an order of President Barack Obama.
