A bomb hidden in a television set exploded in a house in northwest Pakistan early Sunday, killing at least seven people, in an attack police believe was part of a local feud.

The blast took place in a poor neighborhood on the outskirts of Peshawar, the capital of Khyber Pakhtunkhwa province, which borders Afghanistan.

"At least seven people, two children, one woman and four men, were killed in a bomb blast which took place inside a house," senior police official Kalam Khan told media sources.

Three others were wounded in the blast, he added.

Initial investigations showed the bomb was planted in a rented television set which exploded in a guest room of the house, Khan said.

"The attack appears to be motivated by some personal dispute or enmity," he said.

Peshawar was the scene of a car bomb attack on the residence of a tribal elder in the Pishtakhara suburb earlier this month, in which three people were killed and seven others were wounded.
