Hamas has executed a number of alleged looters after several incidents in which heavily armed gangs attacked food stores and community kitchens in the Gaza Strip this week, sources close to the Palestinian militant group said.

Hamas officials have accused some of the looters of working in collaboration with Israel, which has sealed off aid from entering Gaza for the past two months. Israel has not commented on the allegation.

In one incident, the Hamas-run interior ministry said a police officer was killed and others were wounded when an Israeli drone fired a missile at a police unit chasing criminals in Gaza City.
