Russia claims to have critically injured former al-Nusra Front and current Hay'at Tahrir al-Sham (HTS) chief Abu Mohammad al-Golani in Syria.
Russia's Aerospace Forces said, along with al-Golani, 12 field commanders of HTS were killed.
The ministry said, in a statement, it had deliberately targeted al-Golani following intelligence. The spokesman disclosed that Golani and his men had been bombed by two Russian planes.
“As a result of the strike, the Nusra Front leader, Abu Mohamad al-Golani, sustained numerous shrapnel wounds and, having lost an arm, is in a critical condition, according to information from several independent sources,” Konashenkov said.
"Along with numerous (about 50) security guards, 12 field commanders of Jabhat al-Nusra, including the closest aide of Julani, were also killed," he added.
Al-Nusra Front changed its name to HTS, following a merger with another group. Last year the group severed ties with al-Qaida and rebranded to form Hayat Tahrir al-Sham alliance.
Russia joined forces with Iran and local militia to fight against terrorist groups in Syria.
The ongoing war in Syria has an estimated death toll of 220,000 and about 12 million displaced people, who fled to Turkey, Lebanon and Jordan as well as asylum seekers moving outside the region to Europe.
