The ministry stressed the need to unify local and international efforts in a bid to stamp out terrorism.
A suicide bomber killed himself and four others in a central Istanbul shopping and tourism district on Saturday, wounding at least 36 people in the fourth such attack in Turkey this year.
The blast sent panicked shoppers scurrying into side alleys off Istiklal Street, a long pedestrian avenue lined with international stores and foreign consulates, a few hundred meters from where police buses are often stationed.
