Russia has announced that its missile early warning system detected the launch of two missiles from the central part of the Mediterranean Sea fired towards the sea's eastern coastline, and later confirmed in an Israel statement by Reuters news agency.
Israel initially denied knowledge of the missile launch, but soon after said in a statement to Reuters that it had carried out one joint missile test with the US, of an "anchor" target missile used in anti-missile systems, the news agency reported on Tuesday.
Israel said it carried out a test of a missile, used as a target in a US-funded anti-missile system, in the Mediterranean at (9:15am) 06:15GMT, around the same time quoted by Russian state-run news agency, RIA.
An official from the Israeli Defence Ministry later confirmed that both Israel and the US carried a joint missile test in the Mediteranean today.
Al Jazeera's Paul Brennen, reporting from Jerusalem, said that the confirmation by Israel was unusual.
"Its is highly unusual that Israel should be involved in this joint exercise, as it could draw Israel into the conflict."
The launches took place at 06:16GMT (10:16am Moscow time) and were detected by the early warning system in Armavir in southern Russia, the defence ministry said in a statement quoted by RIA.
It said Sergei Shoigu, defence minister, had already reported to President Vladimir Putin about the event, which comes amid growing expectations of Western military action in Syria.
