GROZNY, May 10. /TASS/. The attack on a checkpoint in Chechnya on May 9 is an isolated case, and there are no organized forces behind it, Chechnya’s acting head Ramzan Kadyrov told reporters on Tuesday.

"What happened was not an action organized by some forces. The situation in the republic is exceptionally stable. There are no illegal armed groups, militants, bands and so on in the republic. There were two people, they came from somewhere and attacked [the checkpoint]. This is an isolated case," Kadyrov said.

Officers of the Interior Ministry and Federal Security Service (FSB) are already working on identifying associates of the attackers. "They have already collected a rather sufficient bulk of information on contacts, conversations, video recordings, etc.," he added.
