MOSCOW: Russia claimed Friday to have killed several top commanders of the Daesh group in an air strike in Syria, including the US-trained "minister of war" who had a $3 million bounty on his head.
"As a result of a precision air strike of the Russian air forces in the vicinity of Deir Ezzor city, a command post, communication centre and some 40 Daesh fighters have been killed," the Russian defence ministry said in a statement posted on Facebook.
"According to confirmed data, among the killed fighters are four influential field commanders including Deir Ezzor emir Abu Mohammed al-Shimali," the ministry said.
Gulmurod Khalimov, who is known as the Daesh group's minister of war and the highest-ranking defector from ex-Soviet Tajikistan, suffered a "fatal injury," it added.
Reports of Khalimov's death have surfaced before, and the Tajik interior ministry said it could not immediately confirm the claim. "We are working with our Russian colleagues to obtain reliable information," a spokesman told AFP.
But a spokesman for the Tajik security services, speaking to AFP, suggested that "this time around" he might have been killed.
"We're checking the information," he said.
In 2016, the United States offered a $3 million bounty for information leading to Khalimov's location or arrest.
Russia's SU warplanes dropped "bunker buster" bombs on the fighters as they were meeting near Deir Ezzor to discuss how to respond to the advance of the Syrian army, Moscow said.
Backed by Russia, Syrian troops on Tuesday broke through a years-long siege imposed by Daesh militants on tens of thousands of civilians in Deir Ezzor.
The Times reported in April that Khalimov, described as the highest-ranking Daesh commander in Mosul, had been killed in an airstrike.
The trained sniper and former colonel, he was apparently wounded in 2015 but survived.
He headed the Tajik interior ministry's special forces unit and received American training before joining Daesh in 2015, pledging allegiance to the jihadist group in a video released in May 2015.
In the footage he warned that he and other Daesh recruits based in the Middle East were "coming" for top officials in the mainly Muslim Tajikistan, including long-ruling President Emomali Rakhmon.
The high-profile defection rocked the country.
Last year, his second wife, herself a former interior ministry official, fled Tajikistan with her three young children to join Khalimov in Syria.
His eldest son, 18-year-old Bekhruz, also tried to join his father in Syria but was detained at the Dushanbe airport, and sentenced this summer to 10 years in prison.
In July, police in Tajikistan killed four of Khalimov's relatives in a gun battle, an interior ministry source has said, and three other relatives were detained.
The source claimed that all of those killed or detained were Daesh "supporters" and said they were intending to flee to neighbouring Afghanistan, but did not offer any proof to back up the claims.
