PARIS (Reuters) - French President Francois Hollande confirmed reports on Friday that four hostages were killed at a siege of a kosher supermarket in eastern Paris. Hollande called for national unity and said the country should remain "implacable" in the face of racism and anti-Semitism. "It is indeed an appalling anti-Semitic act that was committed," he said of the hostage-taking by an Islamist gunman at the Hyper Cacher supermarket in the Vincennes district. Some hostages were seen rushing from the market after heavily armed police broke the siege at the same time as they ended a separate stand-off in northern France involving the two Islamist suspects behind the killings at Charlie Hebdo magazine this week.
