CAIRO/GAZA, Nov 22 (Reuters) - Gazans saw little hope on Friday that International Criminal Court arrest warrants for Israeli leaders would slow down the onslaught on the Palestinian territory, where medics said at least 21 people were killed in fresh Israeli military strikes.

In Gaza City in the north, an Israeli strike on a house in Shejaia killed eight people, medics said. Three others were killed in a strike near a bakery and a fisherman was killed as he set out to sea. In the central and southern areas, nine people were killed in three separate Israeli air strikes.

Meanwhile, Israeli forces deepened their incursion and bombardment of the northern edge of the enclave, their main offensive since early last month. The military says it aims to prevent Hamas fighters from waging attacks and regrouping there; residents say they fear the aim is to permanently depopulate a strip of territory as a buffer zone, which Israel denies.
