A 40-year-old woman and her young son died of suffocation from a firewood heater on Thursday in the Nablus village of al-Naqura, police said. The heater sucked all the oxygen from the room as the windows and doors were sealed, the police statement said. Omaymah Mahmoud and 10-year-old Muhammad were found dead by another son when he returned home, and her husband was taken to hospital in a critical condition, the report added. Police urged people not to leave heaters on overnight.
