A female suicide bomber in northwest Pakistan Thursday attacked police at the scene of a bombing that took place earlier in the day. The two blasts killed seven people.
In the first incident, a remote-controlled bomb exploded in a cart as a police vehicle drove by the Lahori area of the city of Peshawar. Five police officers and a child were killed in the explosion, which wounded more than 18 other people.
A short time later, a woman wearing a burqa approached the site of the roadside bombing. Police say the young woman threw a grenade before detonating her explosive-laden vest. Authorities say the vest did not fully detonate. The suicide bomber and another woman were killed in the blast, which also wounded more than 16 others.
No group has claimed responsibility for the attack.
Attacks by female suicide bombers are rare but not unprecedented in Pakistan. In June, militants said they sent a married couple to carry out a suicide bombing at a police station in another northwestern town. That attack killed 10 people.
Peshawar, which lies near the country's restive border with Afghanistan, has experienced numerous suicide attacks and bomb explosions linked to Taliban and al-Qaida in recent years.
Elsewhere in Pakistan's northwest on Thursday, authorities say three women and two children were killed when explosives stored in a house detonated. It is unclear what triggered the blast in the Khyber tribal region, near the Afghan border.
Some information for this report was provided by AP, AFP and Reuters.
