There were 20 passengers in the van which was heading towards Changa Manga from Raiwind in the Province, according to officials. When the vehicle reached a Balloki Sulaimanki link canal in the outskirts of Lahore, one of its tyres apparently burst and the van fell in the canal.
Thirteen people including four women and a child have been killed. Before the rescue teams could reach the spot, most of the passengers had drowned. A search operation was launched to locate the missing persons.
Though the exact cause behind the accident was being ascertained, officials said a possible tyre burst could be one of the reasons.
A large number of local residents also gathered there and helped in rescue efforts.
