The blast took place in a poor neighbourhood on the outskirts of the capital city.

“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 AFP.

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.
