Russia's Ministry of Defense said on Thursday it would hold naval exercises in the Mediterranean Sea from September 1 to September 8 and that 25 vessels and 30 planes would take part, the TASS news agency reported.
The ministry said the drills would involve carrying out anti-aircraft, anti-submarine and anti-mining exercises.
The drills come amid tensions between Russia and the West over Syria's northern rebel-held region of Idlib. A source said on Wednesday that Russia's ally, Syrian President Bashar Assad, was preparing a phased offensive there.
Also Thursday, the Kremlin described Idlib as a hotbed of terrorists and said not tackling the problem was not a good option.
Kremlin spokesman Dmitry Peskov made the comments to reporters on a conference call while answering a question about the planned naval drills, which he said the difficult situation in Syria justified.
On Tuesday, NATO confirmed to Haaretz a large scale Russian navy buildup in the Mediterranean Sea off Syria. Russian media on Tuesday called the deployment Moscow's largest naval buildup since it entered the Syrian conflict in 2015.
