A critical look into the rise of terrorism

A powerful blast ripped through a park crowded with families in Lahore, Pakistan, on Sunday evening killing at least 70 and injuring more than 300. Many of the victims were women and children. The suicide attacker targeted members of the Christian minority community when they were celebrating Easter Sunday.

On the same day a pipe bomb detonated about 5 miles from Disneyland in California, causing damage to the walls of a shuttered business establishment, according to local authorities. Police said no injuries had been reported.

Lahore's blast has something to do with the continuing sectarian clashes in Pakistan, where religious disputes, even serious confrontations, are often reported. The United States, too, is no stranger to sporadic attempts to threaten its public security.
