KUALA KANGSAR, Dec 13 — Seven people including two police personnel were injured in an accident at KM257 northbound of the North-South Expressway towards Kuala Kangsar today.

District police chief Assistant Commissioner Rozali Ibrahim said initial investigations showed a tanker carrying cement had lost control and crashed into a guardrail.

"Subsequently, the tanker crashed into an oncoming express bus which was heading south towards Ipoh,” said Rozali of the 3.30pm incident.

The seven victims, including two police personnel from the Kuala Kangsar District police, were rushed to Hospital Raja Permaisuri Bainun in Ipoh for treatment.

In the immediate aftermath of the accident, Rozali said all southbound traffic was diverted to exit at Kuala Kangsar toll as authorities attempted to move the wreckage.

Rescue operations were called off at 5.50pm.
