69 people killed, 120 others were injured by suicide bomb attack at a hospital in Quetta in south-west Pakistan.
18 lawyers were among those killed.
The Chief Minister of Balochistan, Sanaullah Zehri, said those injured should be given the best medical treatment and facilities available.
Who was behind the attack? Investigators may have a difficult task ahead – there is a confusing cocktail of militant groups in Pakistan that use the country as a sanctuary.
Local experts believe the attackers may have targeted the lawyers because they were less well-guarded than security or police officers – and because an attack on lawyers, who represent a vocal section of society, is likely to attract high publicity.
The last attack with a high casualty figure in Quetta, with same tactics , took place exactly 3 years ago, on 8 August 2013, when gunmen shot dead a police official, and hours later a suicide bomber detonated a device at his funeral prayers, killing about 30 people, many of them senior police officials. That attack was claimed by the TTP.
