Ambulance and emergency crews in the Gaza Strip found two dead bodies in a Khan Younis home on Thursday. Medical sources told Ma'an that Muhammad al-Haddad and his wife Tahrir suffocated to death after inhaling toxic smoke while heating their home using charcoal. Many Palestinians in the Gaza Strip have to resort to basic methods of heating as a a result of regular power cuts. Israel tightened a land and sea blockade on Gaza in 2007 after Hamas took control of the coastal strip, restricting the movement of goods and the 1.7 million residents out of the 360 square kilometer territory.
