Dubai, 19 April 

Iran reversed its decision to reopen the Strait of Hormuz and warned that it would continue to block transit through the Strait as long as the US blockade of Iranian ports remained in effect.

The escalating standoff over the critical choke point threatened to deepen the energy crisis roiling the global economy and push the two countries toward renewed conflict, even as mediators expressed confidence that a new deal was within reach.

The strait is closed until the US blockade is lifted, Iran's Revolutionary Guard navy said Saturday night. Hours earlier, two gunboats from Iran's Revolutionary Guard opened fire on a tanker transiting the Strait of Hormuz, the British military's United Kingdom Maritime Trade Operations centre said. It reported that the tanker and crew were safe, without identifying the vessel or its destination.

Roughly one-fifth of the world's oil passes through the strait, and further limits would squeeze the already constrained supply, driving prices higher once again. Meanwhile, a 10-day truce between Israel and the Iran-backed Hezbollah militant group in Lebanon appeared to be holding.

The fighting in the Middle East conflict, which is approaching the two-month mark, has killed at least 3,000 people in Iran, nearly 2,300 in Lebanon, 23 civilians and 15 soldiers in Israel, and more than a dozen in Gulf Arab states. Thirteen US service members have also been killed.

Israel says it killed a Hezbollah commander just before the ceasefire

The Israeli army says it carried out a series of strikes that killed more than 150 Hezbollah fighters.

Among those killed was Ali Rida Abbas, who it said was Hezbollah's commander in Bint Jbeil. The southern Lebanese town and its surroundings were the site of intense clashes between Israeli troops and Hezbollah militants in the days leading up to the ceasefire.

Israel gave no evidence to support its claims, and Hezbollah didn't immediately confirm the death of its commander. The ceasefire took effect early Friday.

Iran wants lasting peace,' chief negotiator says

Iran's chief negotiator says his country wants “a lasting peace so that war is not repeated again.”

Parliamentary Speaker Mohammad Bagher Qalibaf made the comments in a televised interview late Saturday, a few days before a ceasefire deadline is set to expire, according to Iranian state media.

“What is fundamental for us is distrust of the United States,” he said. “At the same time, we have good intentions and seek a lasting peace — one that prevents the recurrence of war.”

He said that the Islamabad negotiations didn't address the mistrust, but that the US and Iranian negotiators “reached a more realistic understanding of one another.”

He said that the two sides achieved progress in the Islamabad talks, but disagreement remained on some key issues, including the nuclear program and the Strait of Hormuz.

“The gaps remain wide, and some fundamental issues are still unresolved,” he said. He didn't elaborate with further details.

Lebanon's army reopens some roads in the south

The Lebanese army said in a statement Sunday that it reopened the Khardali road that links the southern city of Nabatiyeh with the town of Marjayoun.

The army said that it also reopened the road that links the port city of Tyre with the village of Bourj Rahhal. The army is also working on reopening other roads, including a bridge on the Litani River in the village of Tayr Filsay.

During Israel's invasion of southern Lebanon over the past several weeks, Israel's air force has destroyed several bridges on the river. After a 10-day ceasefire was declared as of midnight Thursday, the Lebanese army and the Litani Authority have been working on putting up temporary bridges to replace the destroyed ones.

Iran negotiator says Strait will remain closed

Iran's parliamentary Speaker, Mohammed Bagher Qalibaf, says the Strait of Hormuz will remain closed as long as the US imposes a naval blockade on Iran.

“It is impossible for others to pass through the Strait of Hormuz while we cannot,” he said in televised comments aired by Iranian semiofficial media late Saturday.

Qalibaf, who is Iran's chief negotiator with the United States, said that the strait is now under Iran's control, linking the choke point's reopening to the US lifting of its blockade. “If the US does not lift the blockade, traffic in the Strait of Hormuz will definitely be restricted,” he said.

He said that the ceasefire was on the verge of collapse when the US attempted to mine-clear the strait. He said Iran viewed the US attempt as a violation of the ceasefire.

“The situation escalated to the point of conflict, but the enemy retreated,” he said.
