U.S. President Donald Trump issued a dire warning to Iran, telling Tehran to “make a deal” before it’s “too late” after Israel bombarded key Iranian nuclear sites and killed top regime officials overnight.

“There has already been great death and destruction, but there is still time to make this slaughter, with the next already planned attacks being even more brutal, come to an end,” Trump wrote in the early hours of Friday morning. “Iran must make a deal, before there is nothing left.”

Israel launched a massive attack on Iran overnight, striking targets including nuclear facilities, regime officials, military leaders and key atomic scientists. Tehran retaliated with more than 100 drones, according to an Israeli military spokesperson.
