A number of countries have fallen victim to terrorist attacks recently, pointing to the cruelty of extremists and the importance of maintaining high vigilance against terrorism worldwide.

On Jan 20, a terrorist attack on a university campus in northwest Pakistan killed at least 22 people and wounded dozens more. The Taliban claimed responsibility for the attack.

This is not the first time that schools in the South Asian country have been targeted by the Taliban. Just over a year ago, Pakistan experienced one of the deadliest school attacks in its history near Peshawar. More than 150 people were killed, mostly children.
