Two young Afghan nomad girls aged 2 and 3 - were crushed to death when a plane carrying US drug enforcement officials overran the airstrip at a southern Afghan airport on Monday.
The Russian-made, twin-engine An-32 aircraft narrowly missed a truck as it came into land at Bost airport in Lashkar Gah, capital of Helmand province.
It then slammed into a cluster of tents and mud brick houses as around 20 women and children ate rice in their brittle mud brick homes.
Jana Gul, the mother of one of the children said; "I was sitting with my family at home when the plane crashed and destroyed our home. Two children were killed. Three children and two women were wounded."
Two of the 16 people on board the plane - 12 passengers and four crew - were also killed, according to a Canadian military spokesman.
Eight others were wounded and flown by military helicopters to a US-led coalition hospital in Kandahar, about 120 kilometres (75 miles) to the east.
A US official, who spoke on condition of anonymity because of the sensitivity of the situation, said the two dead on the plane were Ukrainian flight crew members.
The US Embassy said several of the 11 Americans on board were injured, but none killed.
The nationality of the other passenger was unclear.
The plane, which seats about 20, was leased by the US State Department and carrying a team from the Bureau of International Narcotics and Law Enforcement Affairs.
A US Embassy spokesman said the plane had left Kabul early on Monday for Lashkar Gah, about 520 kilometres (325 miles) to the southwest.
The plane stopped en route in Kandahar before setting off for Lashkar Gah.
It was not immediately clear from whom the US authorities leased the plane, but private American security firms operating in Afghanistan routinely provide such aircraft to authorities.
The crash was the first of a non-military aircraft since November 2005 when a Pakistani-owned plane carrying cargo for the US-led coalition slammed into mountains near Kabul, killing at least eight people.
On Feb. 3, 2005, a plane on a domestic flight belonging to Kam Air, Afghanistan''s only private airline, also crashed into mountains near Kabul due to bad weather, killing all 104 on board.
