Israel's Prime Minister Benjamin Netanyahu has arrived in Moscow for an official visit that includes talks with Russian President Vladimir Putin.
Netanyahu's talks on June 7 with Putin are expected to focus on the situation in Syria, where Russian warplanes are supporting President Bashar al-Assad's regime.
When they last met in April, Netanyahu and Putin discussed coordination between their militaries in Syria.
Israel has largely stayed out of the Syrian conflict.
But Netanyahu has confirmed that his country operates across the border in order to prevent Lebanese Hizballah militants from obtaining powerful weapons.
Netanyahu said in April that closer military coordination was needed to avoid "potential mistakes, misunderstandings, and incidents" between Israel and Russia.
The two were also expected to discuss bilateral relations.
Netanyahu's visit coincides with the 25th anniversary of the restoration of the diplomatic relations between Israel and Moscow, which happened in 1991 shortly before the dissolution of the Soviet Union.
