- Former bodyguard was also a member of Iran's Revolutionary Guard
- Death comes on the heels of two other high-ranking Iranian military figures
Abdollah Baqeri Niyaraki was also a former member of Iran's Revolutionary Guard. He was in Syria serving as a military adviser to the nation's troops, the semiofficial Fars news agency says
His death comes on the heels of two other high-ranking Iranian military figures, also acting as advisers in the south of the country, who were killed in clashes with insurgents, Fars says.
The presence of Iranian military advisers is another geopolitical complication in war-torn Syria, which is seeing an increase in Russian airstrikes, including around the city of Aleppo, Syria's largest.
Syria's ambassador to Russia, Riad Haddad, was quoted by Russian state media as saying there was "heavy fighting" ahead as Syrian troops braced for a "decisive battle" to retake the city. He acknowledged
that there were Russian airstrikes in the area.
"Our troops, backed by Russian aviation, are encircling the city and preparing for a ground invasion," Haddad said in an interview with the news site Gazeta.ru.
