JERUSALEM/BEIRUT/ISLAMABAD, April 10 (Reuters) - A fragile two-week ceasefire between the U.S. and Iran showed further strain on Friday, a day before they are to negotiate in Pakistan, as Washington accused Tehran of breaching promises on the Strait of Hormuz and Israel struck Lebanon with attacks that Iran has claimed violate the truce.

There was no sign Iran was lifting its near-total blockade of the strait, which has caused the worst-ever disruption to global energy supplies. Tehran cited Israel's ongoing attacks on Lebanon, which included the heaviest strikes of the war on Wednesday, as a key sticking point.

U.S. President Donald Trump said in a social media post late Thursday that Iran was doing a "very poor job" of allowing oil to go through the strait. "That is not the agreement we have!"

In a separate post, he said oil would start flowing again, without saying what actions the U.S. might take.

In the first 24 hours of the ceasefire, which Trump announced on Tuesday, just a single oil products tanker and five dry bulk carriers sailed through the strait, which typically carries a fifth of the world's oil and liquefied natural gas flows and 140 ships a day before the war.

Fresh Attacks Escalate Regional Tensions

FRESH ATTACKS

Israel's military said early on Friday it had struck 10 launchers in Lebanon that fired rockets toward northern Israel on Thursday evening, and that Iran-allied armed group Hezbollah launched a missile at Israel, triggering air sirens.

The missile was intercepted, according to the Times of Israel. Hezbollah said it had targeted Israeli military infrastructure in the northern city of Haifa.

The U.S. and Israel have said the latest ceasefire does not include Lebanon, which Israel invaded last month - in parallel with the war on Iran - to root out Hezbollah.

Disputes Over Ceasefire Scope

But Iran and Pakistan, which acted as mediator, say Lebanon was explicitly part of the deal. Iran's Parliament Speaker Mohammad Baqer Qalibaf, expected to head the Iranian delegation opposite U.S. Vice President JD Vance, said on social media that Lebanon and the rest of Iran's "axis" of regional allies were inseparable parts of any ceasefire.

In a defiant statement, Iran's Supreme Leader Ayatollah Mojtaba Khamenei said on Thursday that Iran would exact retribution for the war.

"We will certainly not leave unpunished the criminal aggressors who attacked our country. We will undoubtedly demand compensation for every single damage inflicted," he said in the statement.

The agreement for a two-week truce, mediated by Pakistan, came just hours before a deadline that Trump said would trigger U.S. attacks on Iran's power plants and bridges and the destruction of "a whole civilization."

Diplomatic Efforts and Negotiations

U.S.-IRAN TALKS SCHEDULED FOR SATURDAY

In Pakistan, authorities were preparing for the first round of U.S.-Iran talks on Saturday aimed at settling the conflict that began with U.S. and Israeli attacks on Iran on February 28.

Iran’s Proposal for Settlement

Iran released on Wednesday a 10-point proposal for a settlement to the war that included maintaining control of the Strait of Hormuz, acceptance of Iran's right to nuclear enrichment, lifting of sanctions and ending the war, including against Hezbollah in Lebanon.

Israeli and Lebanese Positions

While he said Israel would continue attacks on Hezbollah, Israeli Prime Minister Benjamin Netanyahu, whose government rebuffed an offer for direct talks with Lebanon last month, said on Thursday he had given instructions to start peace talks as soon as possible, which would include disarming Hezbollah.

"The negotiations will focus on disarming Hezbollah and establishing peaceful relations between Israel and Lebanon," he said.

A senior Lebanese official told Reuters Lebanon had spent the last day pushing for a temporary ceasefire to allow for broader talks with Israel, describing the effort as a "separate track but the same model" as the U.S.-Iran truce.

Prospects for Peace Talks

Israel was preparing to scale down its attacks in Lebanon, a senior Israeli official said on Thursday. U.S. media outlets reported that Trump said he asked Netanyahu to be more "low-key" in Lebanon.

Another Israeli official said talks with Lebanon were expected to begin in Washington next week. A U.S. State Department official confirmed the U.S. would host next week's meeting to "discuss ongoing ceasefire negotiations."

Hezbollah lawmaker Ali Fayyad said in a statement on Thursday that the group rejected direct negotiations with Israel and the Lebanese government should demand a ceasefire as a precondition to further steps.
