(CNN) -- Amnesty International is demanding the United States stop allowing the export of arms and riot-control material to Egypt, where security forces have cracked down on protests. "U.S. arms shipments to Egypt's security forces must be stopped until there is certainty that tear gas and other munitions, weaponry or other equipment aren't linked to bloodshed on Egyptian streets," Amnesty's Brian Wood, who monitors conventional weapons and arms control, said Wednesday. An American company shipped supplies that feature chemical irritants and riot control agents, Amnesty International said in its statement, with arrival on November 26. The organization said another shipment in August had the "product code of bullets, cartridges and shells, but the latter was also described as 'ammunition smoke,'" which Amnesty said includes tear gas.
