New Zealand Prime Minister John Key announced Monday his country will withdraw its troops from Afghanistan earlier in 2013 than planned. The move is not prompted by the deaths this month of five New Zealand soldiers, including three who were killed Sunday by a roadside bomb. Key said it was "highly likely" the remaining soldiers from the contingent of 145 would be withdrawn in April 2013. He said discussions for the earlier withdrawal began before the five deaths this month. Murray McCully, New Zealand's Foreign Affairs Minister, had announced in May the troops would be withdrawn "in the latter part of 2013."
