ISTANBUL, Aug. 26 (Xinhua) -- Turkish President Recep Tayyip Erdogan on Friday voiced his country's determination to "spoil the game" of terror organizations amid growing deadly attacks following a failed coup bid last month.

"Stop grappling with this nation!" the president said in his speech made at the inauguration of Istanbul's third bridge that links Asia and Europe over the Bosphorus Strait. "The blood that you have been shedding in Turkey, Syria, Iraq and Afghanistan is enough."

Turkey, already overshadowed by a series of terror attacks over the past year, has been rocked by a spate of bombing attacks in the wake of a coup attempt on July 15, with the latest ones hitting a wedding ceremony and a police checkpoint respectively, killing 54 civilians and 11 police officers.

The attacks are blamed on the Islamic State and the Kurdistan Workers' Party (PKK), whose militants are fighting the government forces in southeastern Turkey.

"They are using children as suicide bombers, dressing their small bodies with bombs," Erdogan said in his speech.

Hours earlier, Turkish Prime Minister Binali Yildirim declared a "total war" against terrorism.
