After a bombing in the Pakistani city of Quetta killed at least 67 people, many of them lawyers, the Pakistan Bar Council released a statement Monday condemning the attack and calling for a three-day strike in all of the country’s courts.

The statement said that more than 70 lawyers were killed or injured in the attack, which The Associated Press described as a suicide bombing at a hospital in the capital city of Balochistan province in southwest Pakistan. The lawyers had reportedly gathered at the hospital to mourn the death of Bilal Anwar Kasi, president of the Balochistan Bar Association, who was shot and killed earlier in the day.
