Fallout continues after May 3 US air strikes on Bala Boluk district in Farah province, Afghanistan.

The Afghan government says 140 civilians were killed in the bombings, which have provoked anti-US anger across the country.

US officials acknowledge that civilians were killed but dispute the Afghan's numbers.

Some of the civilian victims of the bombings have suffered severe burns, leading human rights organisations to investigate whether they may have been caused by white phosphorous.

US officials have acknowledged that they use the chemical, which erupts into flame on contact with air, to create smokescreens, light up a battlefield and destroy empty buildings.

The US military has denied knowingly using it as a weapon against people and has released a list of 44 incidents of Afghan insurgents using or possessing white phosphorus ammunition.

Qari Mohammad Yousuf, a spokesman for the Taliban, has said that they did not use it at all.

FRANCE 24 visited the burns unit of Herat hospital, where many of the burn victims from the Farah strike are children. Some suspect their burns may have been caused by white phosphorous, but the doctors there say there is no way to be sure.
