QUETTA, Pakistan -- Explosions claimed by sectarian and separatist militant groups have killed some 115 people and wounded dozens of others in what's been described as one of the bloodiest single days in Pakistan in recent years.
The deadliest attacks on January 10 occurred in Quetta, capital of the southwestern Balochistan Province.
More than 80 people were reported killed in two coordinated blasts -- from a suicide bomber and a car bomb -- apparently targeting minority Shi'a at a Quetta snooker club.

Explosion Kills At Least 11 In Quetta
The attack was claimed by the Sunni militant Lashkar-e-Jhangvi group.
Meanwhile, a number of Sh'ia in Quetta have refused to bury their dead to protest the deadly bombings targeting the Shi'ite minority.
On January 11, members of Quetta's Shi'ite community laid at least 30 bodies, draped in shrouds and placed in coffins, out on the street.
They said they would not bury them until the government improves security in the area. Shi'a also burnt tires and blocked a nearby road in protest.
Earlier in Quetta, at least 11 people were killed by an explosion claimed by the separatist ethnic United Baluch Army.
Balochistan's government has announced three days of mourning for the victims.
In the northwestern Swat Valley, at least 22 people were reported killed by an explosion near Mingora.
Pakistani Taliban are suspected of carrying out that attack.
