On Thursday, israeli forces killed two people in an attack on the northern part of the Strip.
The Israeli military frequently attacks the Gaza Strip, saying the actions are being conducted for defensive purposes. However, disproportionate force is always used, in violation of international law, and civilians are often killed or injured.
