Paris demanded Monday that Britain honor promises to take in migrant children from the notorious "Jungle" camp in the French port city of Calais, adding to pressure following accusations by the Red Cross that London is dragging its heels.

Interior Minister Bernard Cazeneuve said he would press the case during a lunchtime meeting in London with his opposite number in the British government, Amber Rudd.

"There are several hundred isolated minors with family in Britain," Cazeneuve said. "I solemnly ask Britain to live up to its moral duty," he told RTL radio ahead of his London meeting.
