Israel has curtailed gas supplies to the occupied Gaza Strip, causing a major disruption to most families and exacerbating the harsh impact of the cold weather. The amount of gas entering Gaza has decreased by 50% since early December, 15% of what is needed. Euro-Mediterranean Human Rights Monitor, based in Gaza, said 20% of Gaza households do not have gas. A shortage of electricity has worsened the crisis. Gaza's agricultural sector, which depends on gas to run greenhouses has been further hurt by the gas crisis. The Israeli authorities are being accused of causing the gas shortages to intensify pressure on Gaza and push people against Hamas, the group who govern the strip. However, the Israeli ministry of energy has not responded to Al Jazeera's requests for comment.
