Israel says Syria has test-fired three Scud missiles - the first such tests since 2001.

Israeli military officials said their air defense systems detected the missile launches from northern Syria last Friday. They said one missile broke up over Turkey, showering debris on two towns.

Turkish officials say Syria has informed them that the incident was an accident that happened during a military exercise. Turkish authorities say no injuries were reported.

There has been no public comment from Syria.

Israel's military described the tests as an act of defiance toward the United States and the United Nations, which pushed Syria to withdraw its troops from Lebanon this year.

Israeli officials also expressed concern that the missiles could carry chemical weapons capable of hitting Israeli targets.
