President Donald Trump said Thursday that he will decide within two weeks whether the U.S. military will get directly involved in the conflict between Israel and Iran as the conflict stretches to seven days. 

“Based on the fact that there’s a substantial chance of negotiations that may or may not take place with Iran in the near future, I will make my decision whether or not to go within the next two weeks,” the president said in a statement read by Press Secretary Karoline Leavitt in a White House press briefing Thursday. 

The president has been considering whether to strike Iran’s Fordow uranium enrichment facility, its most secure nuclear site, which is buried under a mountain and considered to be out of reach of all but America’s “bunker buster” bombs. 

The announcement comes hours after Israel’s defense minister threatened Iran’s supreme leader after a missile strike wounded at least 240 people in and around the Soroka Medical Center in the southern city of Beersheba. 

Israeli Defense Minister Israel Katz blamed Iran’s Supreme Leader Ayatollah Ali Khamenei and said the military “has been instructed and knows that in order to achieve all of its goals, this man absolutely should not continue to exist.”

Earlier this week, President Donald Trump said there were no plans to kill Khamenei “at least for now.”
