Turkey's ruling AK Party, the main secular opposition and the nationalist opposition said on Sunday they were in "full support" of security forces and their battle against terrorism, in a joint statement to parliament.
The motion, which the pro-PKK Peoples' Democratic Party (HDP) refused to sign, came a day after twin bomb attacks outside a soccer stadium in Istanbul killed 38 people and wounded more than 150.
The government has blamed the Kurdistan Workers Party (PKK) terrorist organization for the attacks.
