Israel continued on Friday to bombard the Gaza Strip with air raids and artillery shells as it stepped up the deployment of troops and tanks near the besieged Palestinian enclave. At least 119 Palestinians, including 31 children, have been killed and more than 830 wounded since hostilities flared up on Monday. Hundreds of Palestinian families have taken shelter in UN-run schools in northern Gaza to escape Israeli artillery fire.
