Let's bring you a few comments from Gordon Gray, former US ambassador to Tunisia. He tells the BBC that the Gaza ceasefire deal is a “very positive first step” for Israel and Gaza - but says more details are needed. Gray, who is the Kuwait Professor of Gulf and Arabian Peninsula Affairs at George Washington University, describes Donald Trump's 20-point peace plan as "more aspirational than it was detailed" - so further negotiations will have to happen in the coming weeks and months. "It's going to require dogged, determined diplomacy to continue the effort and really dig down into the details," Gray says.
