Pakistani authorities have closed all the schools in the country's largest province, Punjab, following an alert over possible militant attacks.

A government memo obtained Tuesday by the Associated Press says there is intelligence that 13 Taliban fighters from neighboring Afghanistan were planning suicide attacks on schools in Pakistan.

The province's education minister, Rana Mashood Ahmad, announced late Monday that Punjab schools would remain closed till the end of the month. He didn't cite the government alert but said the closures were due to harsh winter weather and heavy fog in the province

The warning comes a week after a breakaway Taliban faction attacked a northwestern university and killed 21 people, mostly students. That university reopened briefly Monday but then closed indefinitely to give students time to recover from the incident.(Agencies)
