The conflict between Israel and Hamas continued for a fourth day on Tuesday, with the total death toll reaching nearly 1,600 people on Monday. Hamas threatened yesterday to execute Israeli hostages in response to increasing Israeli strikes on the Gaza Strip. The latter has been the subject of a “complete siege” since Monday, ordered by the Israeli army. “No electricity, no water, no gas,” announced Israeli Defense Minister Yoav Gallant. On Sunday, Israel declared war on Hamas after the unprecedented surprise attack launched on Saturday by the Palestinian Islamist movement from Gaza.
