Israel, Hamas and the US, mediated by Qatar, are actively discussing the possibility of extending the four-day truce by an additional two days, two sources tell CNN. 

The original deal of a four-day truce to secure the release of 50 women and children was struck with the understanding that the cessation in fighting could be extended by additional days if Hamas was able to produce additional hostages, as CNN has previously reported.

Ten more hostages would grant Hamas one additional day in the pause.  

Israeli and US officials believed that there were more women and children being held in captivity than 50, but agreed to the terms of the deal as Hamas insisted that it needed to use the pause in fighting to gather up additional hostages. 

It was unclear as of Monday morning what information Hamas had offered on additional hostages.
