Colombian president Juan Manuel Santos has won the Nobel Peace Prize.
The Norwegian Nobel Committee rewarded Santos "for his resolute efforts to bring the country's more than 50-year-long civil war to an end".
The committee said the award should also be seen "as a tribute to the Colombian people who, despite great hardships and abuses, have not given up hope of a just peace, and to all the parties who have contributed to the peace process".
It did not cite his counterpart in peace negotiations, Rodrigo Londono, leader of the Revolutionary Armed Forces of Colombia (Farc).
Santos and Londono signed a peace deal last month ending half a century of hostilities that have killed more than 200,000 Colombians - only to see their efforts collapse following a shock vote against the agreement in a referendum six days later.
One of the front runners for the prize was Syria's White Helmets, a volunteer group who rescue victims from the rubble of bombed buildings in the country. People are praising them for tweeting their congratulations to Santos.
