The Palestinian Health Ministry on Tuesday shut down a West Bank school after several students tested positive for swine flu.
The deputy health minister, Anan al-Masri, said at least six high school students in Nablus had been diagnosed with the flu and the school had been closed to prevent further spread of the disease.
There have been about 130 cases of the H1N1 virus in the West Bank. All have been treated and there have been no confirmed deaths.
Hundreds of parents from the Nablus school rushed into local clinics on Tuesday to have their children tested.
The Health Ministry said it had ample resources to treat anyone infected.
