MOSCOW - Russia's defence ministry says another group of its aircraft has left the Russian air base in Syria and is returning home.
Wednesday's announcement comes two days after President Vladimir Putin ordered Russian military to withdraw most of its fighting forces from Syria, signalling an end to Russia's five-and-a-half month air campaign.
The pullout from the Hemeimeen base coincides with the resumption of UN-brokered peace talks in Geneva between the Syrian government and the representatives of the moderate, Western-Backed opposition.
On the ground, a cease-fire has been in effect since late February. Extremist factions - such as the Islamic State group or the al Qaeda-linked Nusra Front - are not part of the truce.
Russia didn't indicate when the next group of planes will leave or how many will be pulled out.
