“In the context of the hotline between [Israel and Russia], the Israelis sent us a request to develop new procedures and open-fire rules to be added to the existing coordination mechanism,” a Russian source told Izvestia, adding that the request was made in an effort to prevent Russian missile systems in Syria from firing at Israeli aircraft by mistake.

“We are currently developing our response and will send it to the Israelis in the context of the agreed upon procedures between the [two] sides,” the source said.
