No missile strike on Damascus after ballistic launches: Russia
Russian radar detected the launch of two ballistic "objects" in the Mediterranean Sea on Tuesday but there was no sign of a missile strike on the Syrian capital Damascus, Russia's state-run RIA news agency said.
A Defence Ministry spokesman told Russian news agencies the launch was detected at 10:16 am Moscow time (0616 GMT) by an early warning radar station at Armavir, near the Black Sea, which is designed to detect missiles from Europe and Iran.
"The trajectory of these objects goes from the central part of the Mediterranean Sea toward the eastern part of the Mediterranean coast," Interfax news agency quoted the spokesman as saying.
The spokesman did not say who had carried out the launch and whether any impact had been detected, but RIA later quoted a source in Syria's "state structures" as saying the objects had fallen harmlessly into the sea. The Russian Defence Ministry declined commenting over the development.

Carried out joint missile test with US in the Mediterranean: Israel
Israel said it carried out a test of a missile, used as a target in a US-funded anti-missile system, in the Mediterranean.
Israel said it was unaware of any ballistic missile launch being conducted in the eastern Mediterranean. "We are not aware, at this time, of such an event having occurred," a military spokeswoman in Jerusalem said.
The Israeli Defence Ministry said the test was conducted at 9:15 a.m. (0615 GMT), about the same time that Russia's state-run RIA news agency reported that Russian radar had detected the launch of two ballistic "objects" in the Mediterranean.
Russian Defence Minister Sergei Shoigu had informed President Vladimir Putin of the launch. Russia opposes any outside military intervention in the Syrian civil war, and a Defence Ministry official had earlier criticised the United States for deploying warships in the Mediterranean close to Syria.
The United States has been preparing for a possible military strike in Syria following what it says was a chemical weapons attack by Syrian government forces. Damascus denies carrying out such an attack.
