US President Donald Trump on Monday said he hopes to reach the second phase of the Gaza peace plan “very quickly” and warned Hamas of “hell to pay” if it does not disarm soon.

Trump made the remarks during a press conference with Israeli Prime Minister Benjamin Netanyahu in Florida. He said Israel has “lived up to the plan 100%” despite ongoing military actions in Gaza.

The Gaza ceasefire, which began in October, envisions a technocratic government in Gaza, disarmament of Hamas, withdrawal of Israeli troops, and reconstruction of the territory. Trump said reconstruction could “begin pretty soon.”

Trump also warned Iran that the US could carry out further strikes if the country resumes its ballistic missile or nuclear weapons programmes. Iran’s top adviser, Ali Shamkhani, responded that any aggression would receive an “immediate harsh response.”

Trump said the focus now is on ensuring Hamas disarms “in a fairly short period of time” so that the peace plan can progress. He stressed that Israel is following the plan and expressed concern mainly about the actions of other parties.

The leaders also discussed regional tensions, including Syria and Lebanon’s Hezbollah group. Trump said he hopes Israel can maintain peaceful borders with Syria under its new leadership.

Since the ceasefire began, at least 414 Palestinians have been killed by Israeli military operations in Gaza, while Israel has reported three soldier deaths during the same period.
