GAZA CITY, Gaza Strip (AP) — Thousands of Hamas supporters waving the movement's green flag marched through the streets of Gaza Saturday for the funeral of a militant leader and high-profile former prisoner who was mysteriously shot dead, as the group's leaders pledged retribution. Hamas, the Islamic militant group that rules Gaza, said Faqha was shot four times in the head with a silenced gun and blamed Israel for "assassinating" him, but provided no proof to support the accusation. Faqha was sentenced to nine terms of life imprisonment for directing suicide bombing attacks against Israelis.
