 Well, I've been in touch with Egyptian mediators who are directly involved in these talks. So what they've told NPR is that Hamas is actually this time around showing more flexibility than it ever has. The impasse has consistently been that Hamas is demanding a full ceasefire before it releases any civilian hostages, and Israel's government has refused to accept that. The new kind of optimism here is that Hamas is saying, okay, we'll release civilian hostages in the first six weeks.
