AL-MAZRA'A ASH-SHARQIYA, West Bank, July 13 (Reuters) - Frustration among Palestinians grew towards the United States on Sunday as mourners packed the roads to a cemetery in the Israeli-occupied West Bank town of Al-Mazr'a Ash-Sharqiya for the burial of two men, one of them a Palestinian American, killed by settlers.

A Palestinian American man was beaten to death by settlers in the Israeli-occupied West Bank, says the Palestinian Health Ministry, prompting his family to demand that the U.S. lead an investigation.
