Israel Imposes 'Complete Siege' on Gaza as Hamas Rockets Escalate

Israel has ordered a "complete siege" of the Gaza Strip, cutting off supplies of electricity, food, and fuel to the region, following a surprise attack by Hamas. Air raid sirens sounded in Tel Aviv and Jerusalem after Hamas launched rockets at both cities. The European Union is convening an emergency meeting to address the situation, while Russia and Iran have called for a ceasefire. The conflict has resulted in hundreds of casualties and has raised concerns about a regional war. Israel's central bank is selling foreign reserves to support its currency, and oil prices have jumped 4% in response.
