Israeli Defence Minister Israel Katz has said that “Hamas must understand that the rules of the game have changed” after the country unleashed its deadliest strikes on Gaza since a ceasefire began in January, AFP reports.

“If it does not immediately release all the hostages, the gates of hell will open, and it will face the full might of the IDF (Israeli Defence Force) in the air, sea and on the ground until its complete destruction,” the Israeli defence chief was quoted as saying in a ministry statement as he visited the Tel Nof airbase.
