By Andrew Gray, Andrea Shalal and Kanishka Singh TURNBERRY, Scotland/WASHINGTON (Reuters) -U.S. President Donald Trump said on Sunday Israel would have to make a decision on next steps in Gaza, adding he did not know what would happen after the collapse of ceasefire and hostage-release negotiations with Hamas.

Israel and the United States on Thursday pulled their diplomats back from negotiating a cease-fire with Hamas, setting back a potential end to the War in Gaza that was believed to be a real possibility just weeks ago.
