and you don't know where all of them are? >> we don't know. because, on the ground, nobody can move. nobody can make a list. nobody can say about this, it's a war. >> reporter: abu marzouk, who is designated a terrorist by the u.s. government, also claims that around 60 of the hostages have been killed in israeli air strikes. we cannot independently confirm that. but the chaos and devastation in gaza are plain to see. today, cbs news producer marwan al-ghoul sent us this report from a refugee camp. palestinian media say it was hit late at night by an israeli bombardment. >> at least 20 were killed in this place. women still here. women body under this, also children. >> reporter: there is new hope here tonight in israel and also in gaza. but the hostages aren't out yet. the relief group red crescent would take them from hamas and hand them over to israel's military. a u.s. official said today that they will need immediate medical attention because they have been held in "abhorrent conditions." jericka?

>> well, there is definitely that added pressure because you want to do everything you can to serve our customers. many of the customers during this time period travel only one time here so it's critically important we are doing our absolute best to deliver for them. >> reporter: the wet, windy weather is already a factor on the roads, with more than 49 million expected to drive this week. some choosing to move up their plans and leave as soon as possible. >> we both got done with class and the weather is kind of not great, so we didn't want to travel at night. >> reporter: aaa says the worst time to drive tomorrow will between 10:00 a.m. and 6:00 p.m. so far, because of the storm, we have only seen a handful of cancellations, which is good news for the airlines because tomorrow is expected to be the busiest day to fly ahead of the holiday. jericka?
