(JTA) – The body of a missing Israeli teen was found overnight Thursday, April 26, bringing to 10 the number of teenage hikers killed by a flash flood during a hike in southern Israel. Two Palestinian children also died from flooding in the West Bank, Haaretz reported, as the region has been lashed by intense spring rains. The nine girls and one boy killed at Nahal Tsafit, south of the Dead Sea, were taking part in the Bnei Zion pre-army program. Some 15 teens were rescued mostly unharmed. Three staff members, including the director of the trip, have been arrested for possible negligence, Haaretz reported. Weather agencies had issued flood warnings for the region after unusually heavy rainfall on Wednesday.

Israel Television News reported that one of the girls killed had written text messages the day before Thursday’s trip saying she was worried about their safety. “I can’t believe I’m actually going hiking in weather like this. It doesn’t make sense to go to a place that’s completely flooded. It’s tempting fate. We’re going to die – I’m serious,” the girl, 18, wrote on the messaging application WhatsApp. Funerals for seven of the victims took place Friday, drawing thousands of mourners.

The Ministry of Education had warned schools not to hike in the area, according to Channel 10 news. “The trip was not reported to us, our situation room was not told in advance and we did not give any permission for such a trip,” the ministry said in a statement.
