KABUL (Reuters/AFP) - Afghanistans Taliban rejected on Tuesday a US military accusation that the insurgent group was using white phosphorous ammunition. The US military claimed on Monday it had documented 44 incidents of Afghan insurgents using or possessing white phosphorous ammunition, in response to a Reuters report last week of the first known casualty from the chemical. US and Nato forces acknowledge they use the chemical - which erupts into flame on contact with the air - to create smokescreens, illuminate the battlefield or destroy empty buildings, but they deny knowingly using it on people. Qari Mohammad Yousuf, a spokesman for the Taliban, said the movement did not use it at all. We neither have nor use phosphorous. The Americans have used it in many operations and now want to attribute their tyranny to the Taliban, he said by phone from an undisclosed location. In a statement posted on website www.alemarah1.org, the Taliban offered to cooperate with any possible investigation to show they were not using the material. Reuters reported last week that US military doctors had confirmed they had treated an 8-year-old girl with white phosphorous burns in hospital. Her case was not on the list the military released on Monday. In the girls case, the military says it believes no rounds fired by Western forces fell near her house when she was hurt, and that a mortar fired by the Taliban may have been to blame. The girls father told Reuters their house was hit by a volley of artillery fired by Western troops. Human Rights Watch has urged the military to release more details of the incident. In Mondays list of 44 incidents, Western forces reported fighters had actually fired the rounds in just 11 cases. In eight, they were used or found in homemade bombs. In the 25 other cases, they were found unused, usually scattered among caches of other weapons and ammunition. White phosphorous is common in the arsenals of most armies, including the Soviets who fought in Afghanistan throughout the 1980s. Meanwhile, another 98 Afghan girls were rushed to hospital Tuesday in the latest in a spate of mysterious poisonings to hit three schools north of Kabul in a fortnight, officials said. The children fell ill as they entered the school building in the small town of Mahmud Raqi, about 70km north of the capital, teachers and students told AFP. There was a strange smell and some students fainted, others felt sick, said a teacher named only Humaira. Soon nearly all the students at the Aftabaki Girls High School felt ill, she told AFP. A doctor dealing with the case said that the school had apparently been filled with gas overnight, and that insurgent groups opposed to the education of girls could be responsible. Ambulances and police vehicles rushed the affected children to the provincial hospital, said another teacher, Turyalai Khan. We admitted 98 schoolgirls and a few teachers today in our hospital with symptoms of semi-consciousness, weakness, vomiting, headache and dizziness, the head of the hospital, Ahmad Khalid Anayat, told AFP. They became ill apparently from some poisoning gas they respired, he said. Jan Agha, a doctor dealing with the latest case in Mahmud Raqi, capital of Kapisa province, said enemies of Afghanistan - a phrase that refers to various insurgent groups - could have been responsible.
