Pakistan said Saturday Saudi Arabia, Turkey and Egypt will send their top diplomats to Islamabad for talks aimed at ending the Iran war.

More than two dozen U.S. troops have been wounded in Iranian attacks on Saudi Arabia's Prince Sultan Air Base in the past week, according to two people who have been briefed on the matter.

Iranian-backed Houthi rebels claimed a missile launch toward Israel early Saturday, their first since the war in the Middle East started. The Israeli military said it intercepted the projectile.

The war, now marking its one-month anniversary, erupted after the United States and Israel attacked Iran, which retaliated with strikes against Israel and neighboring Gulf Arab states. The conflict has upended global air travel, disrupted oil exports and caused fuel prices to soar. Iran's stranglehold on the Strait of Hormuz, a strategic waterway, has also exacerbated the economic fallout of the war.

Iran appears to be setting itself up as the gatekeeper for the Strait of Hormuz, the world's most important artery for oil shipments. The move could cement Tehran's de facto chokehold over the crucial waterway and formalize its ability to keep its own oil flowing to China.

Iranian communications to the United Nations maritime authority and the experience of ships transiting the strait suggest the creation of something akin to a "toll booth." Ships must enter Iranian waters and be vetted by Iran's Islamic Revolutionary Guards Corps. At least two vessels have paid for passage.

As fears of a wider regional conflict escalate following U.S. and Israeli strikes on Iran that began in late February, Pakistan has emerged as an unexpected mediator, offering to help bring Washington and Tehran to the negotiating table.

Islamabad isn't often called on to act as an intermediary in high-stakes diplomacy, but it's stepped into the role this time for a number of reasons, both because it has relatively good ties with both Washington and Tehran and because it has a lot at stake in seeing the war resolved.

Group of Seven foreign ministers met on Friday in France to discuss the Russia-Ukraine conflict, with deep divisions apparent over the U.S.-Israeli war with Iran, following U.S. President Donald Trump's repeated complaints that America's allies have ignored or rejected requests for help in the military operation and in confronting Iran's retaliatory attacks, including the closure of the Strait of Hormuz to most international shipping.

U.S. Secretary of State Marco Rubio joined his counterparts from the G7 just 24 hours after Trump's latest round of insults lobbed at NATO and as instability in oil markets persisted with the Iran war entering its fourth week along with uncertainty over the status of potential negotiations to end the crisis.

The Saudi Embassy in Beirut said in a statement Friday that the decision is related to the “repercussions of the current events” taking place in Lebanon.

The embassy added that Saudi Arabia’s travel ban to Lebanon has been in place for years.

In a letter Friday to the Israeli military’s chief of staff, Lt. Gen. Eyal Zamir, mothers of soldiers called for an end to the further ground offensive into Lebanon.

The group, Parents of Combat Soldiers, includes 600 military parents. The letter said the military was receiving orders from politicians who are ready to “sacrifice” its children, and urged Zamir to focus on a political solution. “Four soldiers have already been killed in Lebanon, how many more will sacrifice their lives in vain?!” said the letter.

Israel launched a new wave of strikes on Iran and threatened on Friday that its attacks "will escalate and expand" after U.S. President Donald Trump claimed talks on ending the war were going well and gave Tehran more time to open the Strait of Hormuz, though there have been no signs of Iran backing down.

With stock markets reeling and economic fallout from the war extending far beyond the Middle East, Trump is under growing pressure to end Iran's chokehold on the strait, a strategic waterway through which a fifth of the world's oil is usually shipped.

Humanitarian organizations under intense strain because of the United States' steep cuts to foreign aid say they are scrambling to find the funds needed to respond to the war in the Middle East, where millions of people have already been displaced by the widening conflict.

U.S. President Donald Trump's decision last year to dissolve the U.S. Agency for International Development — once the world's leading donor of humanitarian assistance — forced aid groups around the world to fire tens of thousands of staffers and shutter lifesaving programs. Now, some of those same groups are struggling to mount a response in the Middle East. Already, the United Nations' refugee agency, UNHCR, estimates 3.2 million people inside Iran and 1 million people in Lebanon have been displaced since the U.S. and Israel launched strikes against Iran on Feb. 28.
