Ankara: Turkish President Tayyip Erdogan has accused Russia of providing anti-aircraft weaponry and rockets to militants of the outlawed Kurdistan Workers Party (PKK), government officials said on Monday, confirming reports in local media.
Speaking to reporters on board his airplane after a visit to the southeastern province of Diyarbakir over the weekend, Erdogan accused Moscow of transferring weaponry to the PKK via Iraq and Syria, the pro-government Star newspaper said.
"At this moment, terrorists are using anti-aircraft guns and missiles supplied by Russia. The separatist terrorist organisation is equipped with these weapons. They have been transferred to them via Syria and Iraq," the newspaper reported Erdogan as saying.
Two Turkish government officials confirmed Erdogan's comments.
The "separatist terrorist organisation" is a Turkish government term for the PKK, which has waged a three-decade insurgency against the state that has left more than 40,000 people dead, mostly PKK militants in the largely Kurdish southeast.
While Erdogan has previously castigated Russia for its support of Kurdish fighters in Syria, the latest comments appear to be the first time he has accused Moscow of supplying arms to the PKK, seen as a terrorist group by Turkey, the United States and Europe.
However, Deputy Prime Minister Numan Kurtulmus was relatively upbeat on Monday about the outlook for relations with Russia, a rare departure from months of tough rhetoric after Turkey shot down a Russian warplane last year.
"Neither Russia nor Turkey can afford to sacrifice their relationship with each other," Kurtulmus, the government's official spokesman, told a news conference.
"I wish such tensions had never emerged, but I believe that Turkish-Russian ties can be fixed in a short while. These two countries have no problems that cannot be overcome. I hope that these issues will be solved through dialogue."
He did not directly address Erdogan's comments about Russian military support for the PKK.
Ankara also considers the Syrian Kurdish YPG fighters to be terrorists and has been enraged by both Russian and US backing for the militia in its battle with IS in Syria.
NATO member Turkey is part of the US-led coalition against IS in Syria and is also a vocal opponent of Syrian President Bashar Al Assad.
Moscow backs Assad but says it also supports the Syrian Kurds in the struggle against IS.
Relations between Ankara and Moscow hit their worst point in recent memory after Turkey shot down the Russian plane over Syria last year, prompting a raft of sanctions from Russia.
Russian President Vladimir Putin in April promised support for Syrian Kurds, saying they were a serious force in the fight against terrorism.
Moscow has accused Ankara of hindering Kurdish forces in their battle against IS and of using the fight against terrorism as a pretext to crack down on Kurdish organisations in Syria and Turkey.
