ISLAMABAD: Britain is working with the US to ensure a ceasefire between Pakistan and India endures and that "confidence-building measures" and dialogue take place, British Foreign Minister David Lammy said on Saturday.

"We will continue to work with the United States to ensure that we get an enduring ceasefire, to ensure that dialogue is happening and to work through with Pakistan and India how we can get to confidence and confidence-building measures between the two sides," David Lammy told British news agency 'Reuters' in Pakistan's capital Islamabad at the end of a two-day visit.

"These are two neighbours with a long history but they are two neighbours that have barely been able to speak to one other over this past period, and we want to ensure that we do not see further escalation and that the ceasefire endures," David Lammy said.

Asked about India's suspension of the Indus Water Treaty, potentially squeezing Pakistan's water supply, David Lammy said: "We would urge all sides to meet their treaty obligations."

David Lammy said Britain would also continue to work with Pakistan on countering "terrorism", saying that it is "a terrible blight on this country and its people, and of course on the region."
