Storm Byron has hit Gaza and worsened the humanitarian crisis in the Palestinian territory. Heavy rains have flooded tent camps and have left Palestinians in dire conditions on Thursday. Aid groups say Israel hasn't met its ceasefire agreement to allow 600 trucks of aid into Gaza daily. The U.N. agency for Palestinian refugees warns that cold, overcrowded and unsanitary conditions increase illness risks. The Palestinian Civil Defense has reported more than 2,500 distress calls because of storm damage. Senior Hamas official Khaled Mashaal has urged for more aid and infrastructure rehabilitation. The ceasefire agreement remains at a critical point with both sides facing obstacles.
