“No, I do not have such information,” Bogdanov told reporters when asked whether Moscow was aware of Iran’s military base near Palmyra.
Speaking further, the senior official noted that Russia was urging to avoid the escalation of tensions in the region after Israel's strikes on Syria.
“We call on everyone to be calm, to prevent a very dangerous escalation in countries of the region,” Bogdanov told reporters.
The statement comes several days after Israeli Defense Forces released footage allegedly showing the downing of an Iranian drone by an Israeli attack helicopter and the subsequent airstrike against it on the Syrian soil.

The Israeli attack prompted response fire from the Syrian air defense systems. In the second wave of the attack, the Israeli forces struck 12 targets in Syria, including Syrian air defense batteries and Iranian military facilities, the country's Defense Forces (IDF) said.
At the same time, Iran dubbed Israel's reports of a downed drone "ridiculous," saying that the Islamic Republic had only an "advisory, not a military presence" in Syria.
Iran has already been accused by Israel, the US and some of their allies of providing arms to the Hezbollah movement that is fighting terrorists alongside the Syrian army. Tehran has denied the claims, though admitted its political support for the Shiite movement.
