"We have paid our attention to the reports of the transportation by the helicopters having no identification marks of IS Afghan wing's militants as well as arms and ammunition for them, now in the east of Afghanistan," Zakharova said at a regular press briefing adding that a member of the Iraqi parliament's lower house publicly said these vehicles belonged to the United States.
The spokeswoman continued by saying that the transportation of 50 armed extremists and a container with arms and ammunition by the 'unidentified' helicopters to the Afghan cave complex was reported. This was done, according to Zakharova, to support the terror group in the area that had launched an offensive toward Tora Bora.
Up until now, neither Afghan authorities, nor the leadership of US or NATO forces in the country have provided reasonable explanations for the increased number of aircraft noticeably providing support to Daesh militants in various Afghan regions, the Foreign Ministry's spokeswomen noted with concern.
The issues of the unidentified helicopters in Afghanistan was voiced by Russia's Foreign Minister Sergei Lavrov in late May. The top diplomat's concern came after Afghan parliamentarians expressed their own reservations about the flights of such helicopters, which they considered to originate from the United States. Apart from this, the witnesses confirmed that after dropping something off on the territories under the terrorists' control and landing there, these unidentified aircraft would then return to the military bases where US troops were stationed, Lavrov said.
The Tora Bora cave complex was known for harboring Osama bin Laden, late leader of al-Qaeda terror group (outlawed in Russia), in 2001.
Afghanistan has been suffering from instability for years, with government troops fighting against the Taliban, Daesh and other extremist groups.
