At app. 2pm on Thursday 25 February 2010, IOF forces positioned on the northern border with Gaza opened heavy fire on Palestinian workers who were removing the rubble of destroyed buildings. These workers collect rubble to sell it to brick factories which recycle it into bricks. This is the only source of bricks for construction that is available in the Gaza Strip, which suffers from an acute shortage in construction materials due the Israeli siege. No casualties or injuries were reported in this incident.
