Vienna, (IINA) - In response to Russian allegations, Turkish Foreign Minister Mevlut Cavusoglu vowed on Tuesday to his Russian counterpart Sergei Lavrov that he would resign if Moscow provided any evidence showing that Turkey is helping ISIS, Anadolu Agency reported.

In Austria's capital Vienna for an International Syria Support Group (ISSG) meeting, Cavusoglu told Lavrov that he disagreed with the claims that Turkey turned a blind eye to the terrorist organization ISIS, according to witnesses of the exchange who do not want to be identified.

"You are a serious diplomat and one of the most experienced diplomats among us, you should not rely upon such frivolous claims", Cavusoglu said to Lavrov during the meeting, which was shown live in a separate room with other diplomats.

"I am ready to resign if you have any evidence that Turkey helps Daesh", he added using an alternative name for ISIS.

Turkish President Recep Tayyip Erdogan had also condemned the claims that Turkey supported ISIS.

"The portrayal of Turkey as a country that helps Daesh is, excuse me if this will sound harsh, despicable", Erdogan said Wednesday.

Moscow has regularly claimed that Ankara had provided help to ISIS, namely in the form of oil purchases from the terrorist group.

A total 24 representatives, from 20 countries and four international organizations, attended the meeting in Vienna to seek a solution to the five-year Syrian civil war.
