At least four members of a Palestinian family have been killed and 30 other people wounded after a previously unexploded Israeli bomb detonated in a home in a refugee camp in Rafah. The bomb, thought to be from the Israeli assault of Gaza last year, reportedly exploded as workers helped the family clear rubble from a house destroyed in the assault. According to the Guardian, more than 70 Palestinians have been killed or injured by unexploded ordnance since the war ended.
