A number of short-range ballistic missiles had been launched inside Syria this week, a NATO official said on Wednesday.

"Allied intelligence, surveillance and reconnaissance assets have detected the launch of a number of unguided, short-range ballistic missiles inside Syria this week," the official told Xinhua by phone.

"We do not know the details of the missiles, but trajectory and distance travelled indicate they were Scud-type missiles. The missiles were fired from inside Syria and they impacted inside Syria," he said.

The NATO official said no missile landed in Turkish territory and the military alliance had no information about casualties and damage on the ground.

However, the news cannot be verified from the Syrian side at present.
