The SSP sector-II Motorway Police, Farhat Ali Junejo told Dawn that the patrolling of the Motorway Police was affected as its 11 cars and two motorcycles had been burnt during the violence followed the Dec 27 incidents.

He said there were visibility problems due to fog but could not give exact numbers of fog related accidents.

However, he said that they were increasing their patrolling and guiding commuters for safety measures.

He said that an area of 11 kilometres near Kandiaro and five kilometres near Moro were dangerous due to diversions there especially during foggy weather and the matter had been reported to the authorities.

Commuters should clear their windscreen, rear glass and side mirrors and keep safe distance from other vehicles, he advised.
