PESHAWAR: A bomb planted outside a house in Charsadda exploded on Monday and killed at least three people, including a woman and two children, DawnNews reported.

According to police, unknown miscreants planted the bomb outside the home of a local, which exploded causing a nearby house to collapse.

In the blast, a woman died along with two children while her husband and another child were receiving treatment at a hospital.

Charsadda lies close to Pakistan's troubled northwestern tribal region where troops have been locked for years in deadly battles with insurgents.

The city has seen attacks by militants in the past few years, with targets ranging from civilians to policemen and other law enforcement personnel.
