MOSCOW – Turkish President Tayyip Erdogan made a telephone call to Russian president Vladimir Putin to update him regarding investigations into the killing of the Russian ambassador on Friday.

Both the leaders also discussed the ongoing conflict in Syria in the purview of developments in the war-torn region.

The envoy, Andrei Karlov, was assassinated on Monday by a Turkish police official who shouted “Don’t forget Aleppo” before opening fire at Andrey Karlov. He was buried with military honours in Moscow on Thursday.

“The President of Turkey informed Vladimir Putin about how the investigation of the murder of the Russian ambassador to Turkey was going,” the Kremlin said in a statement.

“The close cooperation between Russian and Turkish law enforcement and special services was noted,” it said.

On the Syrian crisis, the two men expressed satisfaction with the end of the operation in Aleppo.

“This has meant that favourable conditions have been created to start the peace process, assuming there will be a cessation of hostilities across the whole territory of Syria and a transition to a political settlement,” it said.
