At least 43 people were killed and 80 injured in a suicide attack targeting a Shia Muslim rally in Pakistan's southwest city Quetta.
The bomber was among the 450-strong crowd and detonated on reaching the main square in the city on Friday, triggering chaotic scenes, with people setting fires as others fled or lay on the ground to avoid ongoing gunfire.
The bomb appeared to target the rally being held for Al-Quds day, an international event held every year by the Shia community, opposing Israel's control of Jerusalem and showing solidarity with Palestinian Muslims.
It is the second time this week the Shia minority has been targeted with a deadly attack.
