DOHA (Reuters) -Qatar's prime minister said on Tuesday relations with Iran have been scarred by an Iranian missile volley at a U.S. airbase in the Gulf Arab state, but that he hoped ties would eventually "come back to normal".

Iran launched missiles at a US military base in Qatar on Monday, in what it said was retaliation for American strikes against its nuclear sites over the weekend. Witnesses reported hearing loud bangs in the sky above the capital, Doha, while videos showed bright flashes in the sky as air defence systems attempted to intercept missiles.
