Moments after announcing an extended ceasefire between Israel and Lebanon, President Donald Trump said "we hope" there's three weeks of "no firing" between the two countries.

"But they do have Hezbollah to think about, and we're going to be working with Lebanon to get things straightened out in that country," he said during surprise remarks from the Oval Office while flanked by Secretary of State Marco Rubio and Vice President JD Vance.

Trump also said he expects the president of Lebanon and the prime minister of Israel to come to the White House "over the next couple of weeks" while the ceasefire is in place, though he did not provide any specifics of such potential travel.

Trump expressed his hope that the Israel-Lebanon conflict will get "worked out simultaneously with what we're doing in Iran."

Israel and Lebanon will extend their ceasefire by three weeks, President Donald Trump announced on social media.

"I look forward in the near future to hosting the Prime Minister of Israel, Bibi Netanyahu, and the President of Lebanon, Joseph Aoun,” Trump wrote.

This comes after a second round of talks between Israel and Lebanon took place at the White House on Thursday.

Exactly one week ago, Trump announced a 10-day ceasefire between Israel and Lebanon.

President Donald Trump told reporters in the Oval Office on Thursday that he is not facing any "time pressure" to secure a deal with Iran.

When asked how long he was willing to wait, Trump responded, "Don't rush me."

"I don't want to rush myself, you know, because every story says, 'Oh, Trump is under time pressure.' I'm not. No, no," Trump said. "You know who’s under time pressure? They are. Because if they don't get their oil moving, their whole oil infrastructure is going to explode. You know what that means, because they have no place to store it."

As for how long Americans should expect to pay higher gas prices, Trump said, "For a little while."

Direct peace talks between Israel and Lebanon at the ambassador level will now be held at the White House, according to a U.S. official.

"President Trump will greet both representatives upon their arrival," according to a U.S. official.

The Defense Intelligence Agency chief told lawmakers that Iran still has an enormous stockpile of munitions, even after the constant bombardment throughout the war until the ceasefire.

“Iran retains thousands of missiles and one-way attack UAVs that can threaten U.S. and partner forces throughout the region, despite degradations to its capabilities from both attrition and expenditure,” Marine Lt. Gen. James Adams, told lawmakers last week.

He added that Iran’s conventional military remains hampered by aging equipment and limited training, likely pushing Tehran to lean even harder into asymmetric tactics. That includes the kind of low-cost drone threats now looming over the Strait of Hormuz, a reminder that Iran can still create outsized disruption through cheap tools.

Those tactics also include cyberattacks.

“Before the current conflict, Iran largely refrained from cyberattacks against the United States, except for a handful of low level disruptive attacks,” Adams said. “However, on 11 March, we observed Iran’s first destructive cyberattack against a U.S. company since 2014, when Iranian cyberattacks conducted a data-deletion attack against a U.S. medical company. Iran almost certainly will continue using cyberattack.”

Adams was likely referring to when an Iranian-linked group hacked Stryker, a Michigan-based medical company. The day after the cyber-attack, Stryker pushed out a statement urging its tools were safe, including the Mako Surgical Robot, a robotic arm that assists in joint replacement surgeries and the LIFEPAK 35, a life support monitor/defibrillator.

Earlier this month, the Cybersecurity and Infrastructure Security Agency warned that Iran-linked cyber groups had targeted systems tied to local municipalities, as well as water and energy networks. In an advisory, the agency said organizations across multiple critical infrastructure sectors had suffered disruptions through “malicious interactions with the project files” and the manipulation of data.

Iran’s defense budget last year was $16.8 billion, which is about 4.2% of its GDP, according to Adams.
