A suicide bomber detonates an explosives-laden vehicle near a railway track in Quetta, in southwestern Pakistan, as a passenger train passes through the city, according to officials and multiple reports. The blast occurs on Sunday and kills at least 23 people, with some outlets reporting at least 24 deaths. More than 70 people are injured, including details that the injuries number roughly in that range across sources. The explosion’s force derails or overturns two passenger train cars, which also catch fire, and footage shared online shows thick black smoke rising from the scene. Authorities describe the attack as taking place alongside the train route rather than on the train itself. Public details on responsibility for the attack are not included in the provided summaries. Reports also indicate emergency response efforts at the site following the blast, as injured passengers and others are treated.
