At least 29 people were injured as a passenger train from Lahore to Rawalpindi derailed Saturday morning in Pakistan, reported local Urdu TV channel Duniya.

The incident took place at about 5:10 a.m. local time when the passenger train derailed at Sara-e-Alamgir, a village on the eastern bank of Jhelum River in Gujrat district in Punjab province.

Gujrat is located some halfway between Lahore, provincial capital of Punjab, and Rawalpindi, a neighboring city of Islamabad, capital of Pakistan.

About five compartments of the train derailed because the rail track was filled with mud brought by the rain in the area, said railway officials. They ruled out the possibility of terrorism.

"It is just an accident," said an official who asked to remain anonymous in a telephone interview with Xinhua.

Heavy monsoon rain lashed Pakistan's eastern Punjab province and southern Sindh province in August, killing over 120 people and affecting nearly five million people.

Some of the injured in the accident have been admitted to hospitals in Rawalpindi and Gujrat, said railway officials. However, they did not say when the railway traffic could be resumed.

Hospital sources said none of the injured was in critical condition.
