Ahead of a meeting with Jordan's King Abdullah, Trump suggested he may withhold aid to Jordan and Egypt if they don't co-operate with his plan to take control of Gaza and resettle the population in the two countries.
Hamas said it would delay the release of Israeli hostages until further notice, accusing Israel of breaching the Gaza ceasefire agreement.
Israel called the move a "complete violation" of the ceasefire deal, which began last month, and said its military was preparing at "the highest level of alert for any possible scenario in Gaza".
