Israeli forces launched a large-scale operation in the Qalandiya refugee camp in occupied East Jerusalem on Wednesday.
The Jerusalem Governorate said dozens of military vehicles stormed the camp before dawn, carrying boxes, equipment and maps.
Soldiers deployed across several neighbourhoods as home raids and searches continued.
Palestinian sources said troops raided the headquarters of the camp's Popular Committee and forcibly removed several residents from their homes.
One family was ordered to evacuate its house completely, while dawn prayers were prevented in all of the camp's mosques.
