Israel has announced the successful launch of a missile in a joint exercise with the US, which came as Washington mulls military intervention in Syria.
"The Israeli defence ministry and the American MDA (Missile Defence Agency) on Tuesday morning at 9.15 (1615 AEST) successfully launched an Ankor-type radar missile," the defence ministry said in a statement on Tuesday.
"The test was launched from the Mediterranean and directed from an army base in the centre of Israel," it said.
Moscow's defence ministry, as cited by Russian news agencies, earlier said its early warning system had detected the launch of two ballistic missiles from the central part of the Mediterranean fired towards the Sea's eastern coastline on Tuesday morning.
The defence ministry statement mentioned only one missile.

The test involved a new version of the Ankor (Sparrow) missile "and was concluded at ... a test range over the Mediterranean Sea," a separate Israeli defence ministry statement said.
The missile was to test missile tracking capabilities, according to local media.
The Russian news agencies said Defence Minister Sergei Shoigu had reported to President Vladimir Putin about the event, which comes amid growing expectations of Western military action in Syria.
"The trajectory of the targets in question was from the central part of the Mediterranean Sea towards the eastern part of the Mediterranean coastline," the Interfax news agency quoted the defence ministry as saying.
Putin, a vocal critic of the West's policies on Syria, has expressed strong doubt that Syrian President Bashar al-Assad was behind an alleged chemical attack on August 21 that has prompted calls for military action.
US President Barack Obama's decision on Saturday to ask Congress to authorise military action against Syria lifted the threat last week of immediate strikes on Assad's government.
Israeli Prime Minister Benjamin Netanyahu said Sunday that the Jewish state was prepared for "every possible scenario" in neighbouring Syria, but President Shimon Peres ruled out Israeli involvement in any intervention.
"It is not for Israel to decide on Syria, we are in a unique position, for varying reasons there is consensus against Israeli involvement. We did not create the Syrian situation," he said.
