New Zealand Prime Minister John Key has expressed deep grief over the fatality of the country’s two soldiers in Afghanistan.

The two soldiers, who were the members of the Provincial Reconstruction Team, were killed during an ambush in Bamiyan province, in which six other Kiwis soldiers were wounded.

Expressing grief over the deaths, Key said, "It's a day of great tragedy where we lose two of our soldiers and obviously they join the other five before them.”

Key added that New Zealand has paid an enormous price by losing seven men in Afghanistan.

But, the Prime Minister underlined that the tragedy would not affect New Zealand’s withdrawal date from Afghanistan. He stressed that New Zealand soldiers should continue on track.

The most recent deaths brought the toll of New Zealand’s soldiers in the Afghan country to seven.

Separately, two members of Afghanistan’s special police were killed, and eleven injured in a battle in the north-east of the region.
