US Secretary of State John Kerry said Tuesday talks with Russia about cooperation in Syria were "making progress", adding he hopes next month to announce new steps aimed at ending the fighting.
Russia and the United States support opposing sides in Syria's five-year war, which has left 280,000 people dead and forced half the population to flee
their homes.
Moscow and Washington co-chair a 22-member contact group working to end the war but a truce brokered by the pair in February has faltered amid heavy fighting.
