KABUL - A harsh winter has killed almost 40 children in Afghanistan in the past month, most of them in refugee camps in Kabul with aid groups warning Sunday of more deaths as temperatures keep falling.

Twenty-four children lost their lives in camps on the outskirts of the capital which houses thousands of Afghans fleeing war and Taliban intimidation in southern Afghanistan.

Others died from cold in the central highlands, public health ministry spokesman Ghulam Sakhi Kargar Noorughli told AFP.

"Over this past one month we have 40 deaths recorded. All have died from cold and are mostly children," he said.

Afghanistan, a landlocked and mountainous country, has suffered its coldest winter in 15 years.

International children's charity Save the Children warned on Sunday that weather conditions were expected to worsen, threatening the lives of more children in the camps.

"Save the Children is warning that even more could die from cold in what is Afghanistan's worst winter for 15 years," the charity group said in a statement, adding that temperatures were expected to drop as low as -17 degrees centigrade.
