A suicide bomb attack has killed at least 70 people at a hospital in Quetta , officials say.
About 120 others were injured in the blast, which happened at the entrance to the emergency department where the body of a prominent lawyer shot dead earlier on Monday was being brought.
The casualties included lawyers and journalists accompanying the body of Bilal Anwar Kasi.
A faction of the Pakistani Taliban has said it was behind the bombing.
Jamaat-ul-Ahrar said it had also carried out the earlier attack on Mr Kasi, who was president of the Balochistan Bar Association and had been shot while on his way from his home to the main court complex in Quetta.
Witnesses described scenes of chaos after the hospital blast, with “bodies everywhere” and survivors shouting for help through the smoke and dust.
Pakistani Prime Minister Nawaz Sharif and chief of army staff Gen Raheel Sharif have both gone to Quetta and will hold talks with security officials.
Gen Sharif met some of those wounded at the Quetta Civil Hospital.
