US President Barack Obama wants "immediate" talks between the Palestinians and Israel to forge a comprehensive Middle East peace agreement, U.S. envoy George Mitchell said on Monday. "The President has told me to exert all efforts to create the circumstance when the parties can begin immediate discussions," Mitchell told reporters at the start of a Palestinian donors' conference in the Norwegian capital. Mitchell, who is en route to the Middle East, said the aim of such talks was "a comprehensive peace and normalization of relations" between Israel and its neighbors, which would also serve "the security interests of the United States."
