The Turkish government last week issued a formal request to NATO for the Patriot missile system to defend its 560-mile with Syria. Turkish forces have returned fire after Syrian artillery strayed across the border several times this year.
NATO Secretary-General Anders Fogh Rasmussen said allies were discussing Turkey's request for the missile defense without delay.
"It is up to the individual NATO countries that have available Patriots -- Germany, the Netherlands and the United States -- to decide if they can provide them for deployment in Turkey and for how long," Rasmussen said in a statement. "Next week a joint team will visit Turkey to conduct a site-survey for the possible deployment of Patriots."
Rasmussen discussed Turkey's security concerns last week with European foreign and defense ministers. There are no plans, he said, to impose a no-fly zone over Syria.
Patriot missiles sent to Turkey during conflicts in Iraq were delivered by the Netherlands. Turkish daily newspaper Today's Zaman said Ankara has twice invoked Article 4 of the NATO charter this year in response to security threats from the Syrian civil war.
