Prime Minister Recep Tayyip Erdogan said today that the death toll in the attacks has increased to 51.
Turkish authorities have blamed Saturday's attacks on a Marxist group with alleged links to the Syrian intelligence agency, but have not named the group. Syria has denied any responsibility for the bombings. Erdogan said the suspects are all Turkish citizens.
Erdogan reiterated that Turkey would act in a "cool-headed" manner although it was "powerful, determined and experienced enough to make the culprits pay" for the attacks. He said investigators are also probing possible security negligence by authorities.
