"On the agenda of the day we have the discussion of issues related to the guarantee of the internal security of the State," Putin said at the beginning of the meeting.
On Monday, Ukrainian drones attacked two airfields in the Saratov and Ryazan regions, killing three servicemen and wounding four soldiers.
These attacks were the most daring and the deepest into Russian territory carried out by the Ukrainian Army since the start of the special military operation in February. The Russian Defense Ministry accused Kyiv of launching "terrorist attacks" against targets on its territory.
On Tuesday, the Briansk region was also attacked with drones, which produced an explosion in the Slava factory a few meters from fuel tanks. A similar event happened in Kursk where a drone strike caused a fire in a fuel depot.
In October, Putin decreed "medium level of reaction" in Crimea and Belgorod, Briansk, Voronezh, Kursk and Rostov, which are Russian regions that border Ukraine. This week's attacks, however, showed a lack of foresight.
Kremlin spokesman Dmitri Peskov said authorities are taking "additional measures" to protect their oil infrastructure in the south of the country.
