NEW: A blast injures 62 people on the outskirts of Quetta, Pakistan

NEW: 28 people were killed in an attack on a Shiite Hazara community

A February attack in the area killed 89 people

Islamabad CNN  — 

A suicide blast Sunday on the outskirts of the southwestern Pakistani city of Quetta killed at least 28 people in an area dominated by Shiite Muslims.

The blast injured 62 others, city police chief Mir Zubair Mehmood told CNN.

The explosion took place in Hazara Town, an area where Shiite Muslims have been targeted in the past.

In February, 89 people were killed and 180 wounded when a suicide bomber targeted a crowded marketplace in the area.

After that attack, Shiite Muslims for days refused to bury those killed in protest of the government’s failure to shield them from recent bloody sectarian violence.

The protest eventually ended after Pakistan security forces killed four suspected militants and arrested seven thought to be responsible for the devastating marketplace attack.
