Kerry urges Iraq to stop arms flow to Syria on Baghdad visit

BAGHDAD (Reuters) - U.S. Secretary of State John Kerry made an unannounced visit to Iraq on Sunday and will urge Prime Minister Nuri al-Maliki to make sure Iranian flights over Iraq do not carry arms and fighters to Syria, a U.S. official said.

Washington believes such flights and overland transfers take place nearly every day and help Syrian President Bashar al-Assad in his efforts to crush a two-year-old revolt against his rule, said the U.S. official, who spoke on condition of anonymity.
