METALS-Copper steadies after Iran missile attack; low stocks lend support

London copper steadied after an early dip on Wednesday, lifted by low inventories and tight supplies amid concerns about any impact from Iran's strike on U.S. forces, while a weaker dollar also supported prices. Iran launched a missile attack on U.S.-led forces in Iraq on Wednesday, hours after the funeral of an Iranian commander whose killing in a U.S. drone strike has raised fears of a wider war in the region.
