ISLAMABAD, April 6 (Reuters) - Two female Pakistani teachers, a female aid worker and their driver were found shot dead on Monday, police and a doctor said, in an area where Islamists have attacked aid groups.
The four, all Pakistanis, were found in a forest near the town of Mansehra, 70 km (40 miles) north of the capital, Islamabad, police said.
"They were all shot dead," said Mohammad Niaz, a doctor at Mansehra’s hospital.
The aid worker belonged to a group promoting education, he said.
Town police officer Rasool Shah said investigators were trying to determine a motive for the killings.
Aid groups poured into the area in North West Frontier Province after an earthquake killed 73,000 people in northern Pakistan in October 2005.
While the area is not known for Taliban insurgents, Islamists wary of aid groups, especially those promoting a greater role for women, have threatened groups and attacked their offices.
Gunmen stormed the office of British aid group Plan International in Mansehra early last year killing four Pakistani staff. (Reporting by Zeeshan Haider; Writing by Robert Birsel)
