    The police put on a high alert during the Easter holidays in late March and arrested a number of suspected terrorists.

    The Philippine cities came under bomb attacks from time to time,with the latest being a blast in a marketplace in General Santos City, Mindanao, in December last year and three simultaneous bombings in Metro Manila, General Santos and Davao in February.
