GAZA CITY, Gaza Strip — Israeli ground forces made their deepest foray yet Sunday into Gaza's most populated area, with tanks rolling into residential neighborhoods and infantry fighting urban warfare in streets and buildings with Hamas militants who kept up their rocketing of southern Israel.
An Israeli army spokeswoman said residential neighborhoods in Gaza are riddled with homemade bombs and booby traps, including mannequins placed at apartment entrances to simulate militants and rigged to explode if soldiers approach.
