At least seven Palestinian children were injured Sunday south of Nablus after settlers threw stones at them, according to Palestinian sources.

Eight Palestinian girls were lightly injured by settlers from Yitzhar who whisked rocks in their direction and then drove away, AFP reported, quoting an unnamed Palestinian Authority official.

Palestinian news agency Ma’an reported that settlers threw rocks that smashed the windshields of two buses, injuring seven kids as they returned from a school trip. They were rushed to Rafedia Hospital in Nablus, Ma’an added, citing Ghassan Daghlas, who monitors settlement activity in the northern West Bank, as well as an unnamed PA official.

The IDF confirmed the occurrence and stated it was investigating the details of the incident.
