GROZNY, July 28 (RIA Novosti) - Chechen President Ramzan Kadyrov has invited some pardoned warlords to join special operations against the remaining militant groups in Russia's troubled North Caucasus republic.

"We need your knowledge and experience in mountain warfare," Kadyrov said on Monday at a meeting with Magomed Khambiyev, former defense minister of the unrecognized republic of Ichkeria, and onetime warlord Shaa Turlayev.

"You know the Nozhay-Yurt, the Kurchaloy and the Vedeno districts very well, and your assistance could be invaluable," Kadyrov said.

In response, Khambiyev said that everybody should join the fight against terrorists and agreed to take part in special operations.

"People like Shaa Turlayev and I, who have combat experience, must help police to fight the terrorists," he said.

Meanwhile, Kadyrov reiterated that the republic had no plans to grant amnesty to militants in the region.

"I say again, there will be no amnesty for militants. Those who decide to return to peaceful life must first face a trial," he said.

Russia's North Caucasus republics have been swept by a wave of violence recently two months after the government formally ended its decade-long counterterrorism operation in Chechnya, which witnessed two brutal separatist wars in the 1990s and early 2000s.

The last terrorist attack to hit Chechnya was on Sunday, when an explosive device was set off by a suicide bomber near a concert hall in the center of the Chechen capital, Grozny. Four senior police officers and one civilian were killed in the blast.
