JERUSALEM (AP) — A leading international watchdog on Wednesday accused the militant Hamas group of abducting, torturing and killing Palestinians during the war in the Gaza Strip last year, saying some of the actions amount to war crimes. According to the London-based human rights group, some 23 Palestinians were shot and killed and dozens more were arrested and tortured by Hamas, which rules Gaza. The Palestinians targeted were either political rivals of Hamas, including members of the Fatah party of Palestinian President Mahmoud Abbas, or people the militant group had accused of cooperating with Israel, Amnesty said. Hamas violently seized Gaza from forces loyal to Abbas in 2007, leaving Palestinians bitterly divided — Hamas ruling Gaza and Abbas governing parts of the West Bank. [...] Hamas has launched thousands of rockets at Israel and fought three wars with the Jewish state.
