U.S. President Donald Trump said on Sunday Israel would have to make a decision on next steps in Gaza, adding that he did not know what would happen after the collapse of ceasefire and hostage-release negotiations with the Hamas militant group.

The Israeli military on Sunday began limited pauses in fighting in three populated areas of Gaza for 10 hours a day, part of measures including airdrops as concerns grow over surging hunger and as Israel faces criticism over its conduct in the 21-month war.
