Israeli army invaded, on Tuesday morning, Aida refugee camp south of the West Bank city of Bethlehem.
Troops conducted a wide scale search in the camp, forced the families out of their houses for three hours and detained some of the youth.
All dittanies were released after soldiers searched their houses and checked their identify cards, local sources reported.
