Britain is working with the U.S. to ensure a ceasefire between India and Pakistan endures and that "confidence-building measures" and dialogue take place, foreign minister David Lammy said on Saturday.

A ceasefire agreed between India and Pakistan appears to be holding, with both sides stressing their commitment to the surprise truce which halted the worst fighting in decades between the nuclear-armed neighbors.

The high-stakes stand-off between India and Pakistan seems to be de-escalating after the United States brokered an immediate ceasefire between the two nuclear powers, but their bad blood has only continued to boil.
