Israeli Defense Minister Moshe Arens is flying to Washington on Sunday to seek approval for Israel's plans to avenge Iraqi missile assaults and to lobby for more military aid, government officials said Saturday.

The one-day trip by Arens kicks off a series of visits by top Israeli officials at a time of growing discomfort here with being left out of the war against Iraq and suspicion that at the conflict's end, Israel may be pressed to concede occupied territory to Palestinians as part of an overall Middle East peace settlement.Foreign Minister David Levy is expected to meet Secretary of State James A. Baker III early this week, and, later in the month, Prime Minister Yitzhak Shamir plans to go to Washington to visit President Bush.
