At least 60 people died and hundreds were injured when three militants attacked a police training academy in Pakistan’s Quetta city late Monday night. Two attackers blew themselves up while the third was gunned down by Pakistani troops.

This was not the first time Quetta had witnessed such a tragedy. Located about eight miles from the city center, the academy has been attacked twice in the past.

The year has been witness to multiple terror attacks with USA Today saying 2016 has been marred by “near daily terror attacks all over the world” and this was just halfway through the year. Iraq remained the country most afflicted by terrorism.

The following were the biggest terror attacks in 2016 so far, in terms of casualties.

1. Karrada bombing, July 2016:

A vehicle filled with explosives detonated just outside a shopping center in a primarily Shiite area in Baghdad’s Karrada neighborhood, leaving at least 292 people dead. The attack was described as the worst to hit Iraq’s capital in the 10 years during which the country has experienced war and insurgency.

The Islamic State group, also known as ISIS, claimed responsibility for the attack which occurred just before the end of the holy Ramadan season.

5. Kabul twin blasts, July 2016:

Two ISIS fighters blew themselves up during a demonstration by members of Afghanistan’s Shiite Hazara minority in Kabul, killing at least 80 people and injuring over 230. This was one of the deadliest attacks Kabul had witnessed since U.S.-led forces attempted to oust the Taliban in 2001.

Afghanistan’s main intelligence agency, the National Directorate for Security, said the attack was planned by Abu Ali, an ISIS militant who was based in Nangarhar province. They also said three bombers were involved in the attack.
