Several Afghan policemen were reportedly killed after they were poisoned in Afghanistan's Helmand province, while 100 schoolgirls fell ill after another case of poisoning at a girls school in the country, local media reported, . 

At least seven policemen were poisoned to death in southern Helmand, Pajhwok Afghan News reported. 

The Taliban, which is once again becoming resurgent in Afghanistan, is said to have gained a stronghold in Helmand in recent weeks. 

However, it is not clear as to which group was behind the latest case of poisoning in Afghanistan. 

In another case of poisoning at a girls school in Afghanistan, 100 schoolchildren were poisoned in western Herat, in the second such incident in days, Pajhwok reported.

Earlier this week, more than 100 schoolgirls and teachers fell ill after being exposed to gas poisoning at their school in Herat. 

Afghan authorities are reportedly investigating if the Taliban is behind the poisoning, given that the terror group seeks to prohibit girls' education. 

In July, too, several schoolgirls had fallen ill after a similar case of poisoning. 

According to Afghanistan's TOLO News, there has been an increase in cases of poisoning at girls schools in Afghanistan in recent months.
