US President Donald Trump threatened on Friday to hit Iran "very hard," as US media reported he was considering renewed heavy attacks as soon as this weekend, including against energy infrastructure targets, with Israel expected to join the campaign.

After more than five months of war, which began on February 28 when the United States and Israel launched strikes on Iran, there appears to be no end to the conflict, with tit-for-tat attacks resuming.

"We'll be hitting him very hard and, you know, at some point they're going to say, 'We just can't take it anymore,'" Trump said on Friday as he hosted a cabinet meeting at the Camp David presidential retreat in Maryland.

The Wall Street Journal later reported that Trump had ordered a fresh attack aimed at convincing Tehran to surrender, which could begin as soon as this weekend, citing unnamed US officials.

CBS News, meanwhile, reported that the United States and Israel were planning joint strikes on energy-related targets, possibly throughout the weekend. Such targets would likely include oil refineries and power plants.

Trump has repeatedly threatened to strike Iran's vital infrastructure throughout the war, vowing last week to destroy a bridge or power plant every time ships in the vital Strait of Hormuz are attacked.

The US president had not yet given the green light for the campaign, but Israel and the US were coordinating, CBS said, citing multiple unnamed sources.

The report comes just days after Israeli Prime Minister Benjamin Netanyahu visited Washington and met Trump and US Defense Secretary Pete Hegseth

Some White House aides voiced strong objections to the plan during the cabinet meeting, the CBS report said.

If the plan went ahead, it would mark the first time Israel has joined attacks on Iran since the initial phase of the war.
