MOSCOW, November 17. /TASS/. Russia has involved ten reconnaissance satellites to provide support for its operation against terrorists in Syria, Chief of the Russian General Staff Valery Gerasimov said on Tuesday.

"Efforts continue to enhance satellite-based reconnaissance for the Middle East region," he reported to Russian President Vladimir Putin.

"Ten imagery and electronic warfare reconnaissance satellites, including civilian-use spacecraft, have been involved in reconnaissance," he said.

"Measures have been taken to redirect and correct the orbits of some satellites to ensure surveying of the territory of Syria with the required periodicity," Gerasimov said.

President Putin earlier demanded to intensify the Russian Aerospace Force’s strikes in Syria after Federal Security Service Chief Alexander Bortnikov reported that the Russian airliner over the Sinai peninsula on October 31 was blown up by terrorists.

The air crash that killed 224 people was the biggest disaster in the history of Russian aviation. After the airliner crash, Russia suspended flights to Egypt.

Russian aircraft have been delivering strikes against facilities of the Islamic State terrorist organization in Syria since September 30 at the request of Syrian President Bashar al-Assad.
