After the killing of Russian envoy in Ankara, there was speculations were rife that Russia and Turkey relation might worsen.

However, both the countries have reportedly agreed that envoy kiiling was an act of "provocation".

Russian President Vladimir Putin termed the incident as an act of disrupting the normalisation of bilateral ties and the "peace process in Syria", reported Turkish state media Anadolu agency.

It was not clear if the gunman, an Ankara riot police member who was later shot dead in a gun fight with Turkish officers, had links to any militant group.

Both the countries have vowed to work together to find out who is behind the murder of Karlov. Russian investigators arrived in Turkey to help on Tuesday.

President Putin is backing Syrian President Bashar-al-Assad in the ongoing conflict in Syria which had led to mass killings of people opposing Assad forces.

While, Turkish government is backing the opposite rebel faction in war-torn Syria.

Both the countries are not on the same page as far Syrian conflict is concerned. This year Turkey had gunned down a Russian jet fighter which had led to tension between both the countries.

The killing of Russian envoy is being seen as the reaction of recent bombing in rebel held Aleppo where hundreds of people were killed last week.

Police have arrested six people over the killing of the Russian ambassador, Turkish state media Anadolu agency  said on Tuesday.

On Monday a policeman had gunned down the Russian envoy Andrey Karlov at a photo exhibition in Ankara.

According to media reports, the policeman shouted "Don't forget Aleppo!" as he gunned the envoy down.

He was later shot dead by members of Turkey's Special Forces.

The ongoing civil war between Assad forces and Sunni rebels have killed around 300,000 people and created a power vacuum exploited by Islamic State.
