Russian radar detected the launch of two ballistic "objects" towards the eastern Mediterranean from the central part of the sea on Tuesday, Russian news agencies quoted the Defence Ministry as saying.
Interfax news agency quoted a ministry spokesman as saying the launch was detected at 10:16 am Moscow time (2.16 a.m. ET) by an early warning radar station at Armavir, near the Black Sea, which is designed to detect missiles from Europe and Iran.
The agencies did not say who had carried out the launch and whether any impact had been detected. The ministry declined comment to Reuters.
Defence Minister Sergei Shoigu had informed President Vladimir Putin of the launch.
"The trajectory of these objects goes from the central part of the Mediterranean Sea toward the eastern part of the Mediterranean coast," Interfax quoted the spokesman as saying.
A ministry official had earlier criticized the United States for deploying warships in the Mediterranean close to Syria.
