FARAH, Afghanistan, April 16 (Xinhua) -- Anti-government militants have attacked and bombed another girls' school in the second attack against education facilities in Afghanistan's western province of Farah within a day, a local official said on Tuesday.

"Armed men blew up Amir Shir Ali Khan High School by explosives in Nawda locality on the outskirts of Farah city, capital of western Farah province Monday night," Mohammad Azim, head of the provincial education department, told Xinhua.

The school building was destroyed but no one has been injured as the school, accommodating over 1,000 students, was closed during the overnight attack, he noted.

An investigation was underway, the official said.

On Sunday night, a girls' school was bombed and destroyed in a similar attack in Tosaak locality of the city, 695 km west of the country's capital, Kabul.

No group has claimed responsibility for the incidents so far.

The Taliban militants had in the past been blamed for such incidents as they were opposing girls' education.

More than 9.5 million Afghan children with around 40 percent of them girls attend 15,000 schools across the country while over 3.7 million school-age children have no access to education due to poverty, conflicts and insurgency, according to education officials.
