KABUL, April 25, (AP): Dozens of Afghan schoolgirls have fallen ill in recent days after reporting a strange odor in their classrooms in northern Afghanistan, prompting an investigation into whether they were targeted by militants who oppose education for girls or victims of mass hysteria. Either way, the reports from three schools within 2 miles (3 kilometers) of one another in Kunduz province have raised alarm in a city threatened by the Taleban and their militant allies. The latest cases occurred Sunday, when 13 girls became sick, Kunduz provincial spokesman Mahbobullah Sayedi said. Another 47 complained of dizziness and nausea the day before, and 23 fell ill last Wednesday. All complained of a strange smell in class before they fell ill.

“I came out from the main hall, and I saw lots of other girls scattered everywhere,” Anesa, a 9-year-old who was hospitalized briefly Sunday, told The Associated Press. “Then suddenly, I felt that I was losing my balance and falling.” None of the illnesses was serious and the girls were only hospitalized for a short time. The Health Ministry said blood samples were inconclusive and were being sent to Kabul for further testing to determine the cause of the illnesses. “This is a matter of concern not only for us but for the families,” Sayedi said, blaming the sicknesses on “enemies” who oppose education for girls. In the capital of Kabul, President Hamid Karzai’s spokesman, Waheed Omar, said any attempt to keep girls out of school is a “terrorist act.”

Kunduz had been relatively quiet until a few years ago when Taleban activity began to increase, threatening NATO supply routes south from Central Asia. Late Saturday, NATO and Afghan troops killed one militant and detained several others in Kunduz province. Girls were not allowed to attend school when the Taleban controlled most of Afghanistan. The group was ousted from power in the 2001 US-led invasion. The Taleban and other conservative extremist groups have been known to target schoolgirls. Elsewhere in Afghanistan on Sunday, hundreds of people blocked a main road in Logar province, west of Kabul, and burned several trucks to protest what they said were civilian deaths in NATO operations.

They gathered hours after NATO said coalition troops killed several insurgents and captured a Taleban sub-commander. In southeastern Afghanistan, a suicide bomber attacked private security guards while they were at a bazaar, killing four Afghans and wounding 12, the government said. Two of the dead and five of the wounded worked for the US Protection and Investigations security firm, an Interior Ministry statement said. The other victims were civilians. The Houston-based company could not immediately be reached for comment. The suicide attacker, who was on foot, targeted the guards at a bazaar in Sahjoy district of Zabul province, the ministry said.
