A female suicide bomber blew herself up outside a hospital in a Bajaur Agency on Saturday and killed at least four people and wounded four others, officials said.
The attack took place in Khar, the main town of Bajaur tribal district bordering Afghanistan where the military has carried out several offensives against al Qaeda-linked Taliban militants.
“At least four people were killed and four others were wounded in the blast outside the main gate of the hospital,” Mohammad Riaz, chief doctor at the government hospital, said.
Local administration official Abdul Haseeb confirmed that it was a female suicide bomber and the casualties.
“It was a female suicide bomber, about 18-20 years old, we have found her legs and head,” he said.
The dead included a security personnel, a hospital worker and two civilians, he added.
Bajaur is one of seven districts that make up Pakistan’s Federally Administered Tribal Areas (FATA). The semi-autonomous region of mountains, valleys and caves is one of the most deprived and ill-educated in the country.
It has been a stronghold for Afghan Taliban, al Qaeda and other Pakistani militant groups, and a battleground between the army and insurgents.
Pakistan has lost more than 3,000 soldiers in the fight against homegrown insurgents but has resisted US pressure to do more to eliminate havens used by those fighting the Americans in Afghanistan.
