Turkish President Recep Tayyip Erdogan vowed Sunday to purge the "virus" within state bodies.

Turkish President Recep Tayyip Erdogan vowed Sunday to purge the "virus" within state bodies, during a speech at the funeral of victims killed during the coup bid he blames on his enemy Fethullah Gulen.

"We will continue to clean the virus from all state bodies because this virus has spread. Unfortunately like a cancer, this virus has enveloped the state.

"We knew this and told all relevant authorities," he warned thousands of mourners at the Fatih mosque in Istanbul.

During a passionate speech, the president paid tribute to the "martyrs" of democracy, insisting that the people were stronger.

"They may have tanks but we have our faith. We will not leave the squares ... but we will continue defiantly.

"I said this yesterday, the people's demand for democracy cannot be swept aside. This is your right."

During the attempted coup, 161 civilians and regular troops lost their lives in Istanbul and Ankara, according to government figures.
More than 100 coup plotters were also killed, the military said.

Despite fears in the West and the United States that Erdogan would wreak revenge, he said: "Don't forget this, we are not vengeful."
