Earlier, local media said one or two "terrorists" entered the school and opened fire indiscriminately, killing and wounding students. The website of local daily Ha'aretz said they might have been armed with explosive belts.
Some reports suggested the terrorists were shot and killed, while other reports from the scene said the incident was ongoing and shots were still being fired.
MDA also said that three of the injured were listed as being in very serious condition and have been taken to Hadassah Medical Center in Ein Karem, while another four were taken to Sha'arei Tzedek Medical Center.
