Colombia has extended a suspension of air attacks on the country's main rebel movement amid a day of marches in support of peace.

Thousands of marchers waved white flags and paraded through cities across the country Thursday to support peace talks between the government and guerrillas, and pay tribute to victims of the nation's armed conflict.

President Juan Manuel Santos led more than 8,000 people through Bogota, marching alongside victims who suffered at the hands of rebels and paramilitary groups.

Speaking at the presidential palace, he announced a one-month extension of the order he gave in March that the military suspend air attacks on camps of the Revolutionary Armed Forces of Colombia

The two parties have been in negotiations in Havana since 2012 to end Colombia's half-century-old conflict.
