The Government has agreed for Kiwi troops to work in a wider radius outside Bamiyan province after two soldiers were killed there on Saturday.

Prime Minister John Key has revealed the two dead soldiers were both in their 20s and did not have a lot of family in New Zealand.

Two New Zealand Defence Force personnel have been killed and six injured in Afghanistan. The NZDF said in a statement the two were serving with the New Zealand Provincial Reconstruction Team.
