At least four people were killed when a cylinder exploded in a van in Pakistan's Sindh province.
Ten other passengers sustained burn injuries. The van was headed to Sehwan Sharif city from Tando Masti Khan town when it caught fire following the huge blast, Xinhua news agency reported.
A fire ignited by the blast killed three persons on the spot while another passenger succumbed to burn injuries on the way to hospital. Officials said the incident happened because the vehicle was poorly maintained.
