ISLAMABAD, July 13 (Xinhuanet) -- Three passenger trains collided early Wednesday near Ghotki in Pakistan's southern Sindh province and many feared dead and injured, private Geo TV reported.

    "Many people may have been killed or wounded," said Rizwan Edhi,an official from Edhi Welfare Trust, a private relief organization.

    The accident occurred at about 4:00 a.m. (2300GMT) at Sarhad station near Ghotki, about 600 kilometers northeast of Karachi, provincial capital of Sindh. A Quetta Express was static in the station for repair when a Karachi Express collided with it from the rear.

    The Quetta Express was bringing passengers from the eastern city of Lahore to the southwestern city of Quetta, when it developed a technical problem.

    Technicians were working on the train when it was hit by the Karachi Express, a night-coach passenger train bringing people from Lahore to the southern port city of Karachi.

    The collision caused three carriages to derail and spill over onto another track where they were struck by the third train Tezgam, which was carrying people from Karachi northward to Rawalpindi, twin city of Islamabad.

    Train traffic has been suspended in the station and relief teams are on their way to the accident site. Police and other law enforcement personnel have been called out since large casualties are feared, said the private TV. Enditem
