A 17-year-old Israeli and his 60-year-old father were lightly injured when a Palestinian Authority (PA) Muslim teen approached them near the PA town of Azzun, east of Qalqilya, asking if they were Jewish.
When the victims responded in the affirmative, the terrorist stabbed them.
The troops provided the civilians with initial medical treatment and Magen David Adom transferred them for further treatment.
Israeli security forces are searching for the terrorist.
