Smoke rises into the sky above the Gaza Strip after an Israeli air strike. Fighting in the war-torn Gaza Strip is raging for a 20th day after Hamas militants launched a surprise attack on Israel, killing at least 1,400 people, mostly civilians. Since the October 7 attack, Gaza's Hamas-run health ministry says more than 6,500 Palestinians have been killed by Israel's relentless retaliatory bombardments, mostly civilians and many of them children.
