NATO is expected to approve a deployment of Patriot missiles to Turkey to bolster its air defences against Syria.
The request from Turkey to the 28-nation alliance was made after weeks of talks with allies about how to beef up security on its 560-mile border with Syria, which is mired in civil war.
NATO foreign ministers meeting in Brussels today for a twice-yearly meeting are expected to support the delivery of the Patriots, which can be used to intercept missiles and planes.
General Richard Myers has told ITV News that the real threat in Syria is from Islamist groups using chemical weapons - not President Assad.
NATO agrees to deploys Patriot missiles along the Syria/Turkey border but denies claims that it is taking an active role in the conflict.
