In the filth and powdered cement of what the Israelis had left of his home yesterday, 81-year-old Mohamed Shaer found his Palestine passport but sought in vain for the only photograph of his wife, Mansoura. She died just three years ago, and Mohamed, in white beard and white robe, smiled when he conceded it was probably for the best that she had not lived to see this day; the home she had shared with him and their two sons, Ibrahim and Mohamed, and their own 17 children, ground into the mud by an Israeli bulldozer that came through the border fence, spitting fire from a machine-gun on the roof while two tanks sent salvoes of shells into the nearest buildings.
