The parents of an aid worker killed after being taken hostage in Afghanistan have been inspired by the work of a charity set up in her name.

John and Lorna Norgrove, whose daughter Linda died during a mission to rescue her in October 2010, travelled to the country to visit projects funded through the foundation they created in her memory.

The couple, from Lewis in Scotland, have used money from the Linda Norgrove Foundation to continue the 36-year-old's work in the war-torn country.

Their trip to Afghanistan was filmed for a BBC documentary, to be broadcast this week to mark the second anniversary of their daughter's death.

They visited a number of aid projects and met her colleagues and friends.

Mrs Norgrove said: "We went back for several reasons: We wanted to visit the projects the foundation was funding, we wanted to meet the people who were helping us to monitor these projects and to implement them, and in particular we wanted to meet with Linda's friends and colleagues."

Mr Norgrove also said their daughter was drawn to work in Afghanistan by the people.
