Rescuers were Tuesday picking their way through rugged terrain and pockets of Taliban insurgency in the search for survivors after a massive quake hit Pakistan and Afghanistan, killing more than 300 people.

The toll was expected to rise as search teams reach remote areas that were cut off by Monday's powerful 7.5 magnitude quake, which triggered landslides and stampedes as it toppled buildings and severed communication lines.

A police official in the northwestern Pakistani city of Peshawar told AFP they had not been able to get in touch with authorities in the district of Kohistan in Khyber Pakhtunkhwa to see how its population of nearly half a million people had fared.

"There is no way to communicate with the officials in Kohistan, the communication system has been disrupted and roads blocked so we cannot say anything about the damage there," the official told AFP.

In other remote areas residents -- including children and the elderly -- were helping with relief work, many of them digging through rubble for survivors.

The bulk of the casualties were recorded in Pakistan, where 228 people were killed, including 184 in Khyber Pakhtunkhwa province, and more than 1,600 injured, disaster management authorities said.

Pakistan army helicopters began evacuating victims Tuesday to Peshawar and Rawalpindi.

The military has also sent medical teams, tents and rations to affected areas, while India -- whose relationship with Islamabad is often prickly -- said it stood ready to help.

For many, Monday's quake brought back traumatic memories of a 7.6 magnitude quake that struck in October 2005, killing more than 75,000 people.

Afghan officials said at least 76 people were confirmed dead and hundreds more injured, with casualties reported from around half a dozen of the country's 34 provinces, and some 4,000 homes reported damaged.

The government has implored aid agencies for assistance.

But large swathes of Badakhshan, the remote province where the epicenter is located, and other areas are effectively controlled by the Taliban, posing a huge challenge to any official aid efforts.
