U.S. President Donald Trump's lead Iran negotiators Steve Witkoff and Jared Kushner have visited the USS Abraham Lincoln aircraft carrier in the Arabian Sea, the US military said, with Washington and Tehran due to hold further talks soon.

Israeli Prime Minister Benjamin Netanyahu will meet U.S. President Donald Trump in Washington on Wednesday to "discuss with him the negotiations with Iran", the premier's office said.

Iran's foreign minister said a fresh round of talks with Washington would take place "soon", while insisting that enrichment was Tehran's "inalienable right" and building trust would take time.

U.S. President Donald Trump said that Washington had "very good talks" on Iran after the two sides held an indirect dialogue in Oman, pledging another round of negotiations next week.

Organizers of an international flotilla of boats carrying humanitarian aid to Gaza announced plans for another mission with more than 100 boats in March.

Campaigners, who organized a similar aid flotilla last year, described the upcoming mission as the biggest civilian-led mobilization against Israel's actions in Gaza. They called on the international community to prevent Israeli forces from intercepting the operation.

Basic services at a camp in northeast Syria holding thousands of women and children linked to the Islamic State group are returning to normal after government forces captured the facility from Kurdish fighters, a United Nations official said on Thursday.

Forces of Syria's central government captured al-Hol camp on Jan. 21 during a weekslong offensive against the Kurdish-led and U.S.-backed Syrian Democratic Forces, or SDF, that had been running the camp near the border with Iraq for a decade. A ceasefire deal has since ended the fighting.

Thousands converged on Friday in northwestern Libya for the funeral of Seif al-Islam Gadhafi, the son and one-time heir apparent of Libya's late leader Moammar Gadhafi, who was killed earlier this week when four masked assailants stormed into his home and fatally shot him.

Mourners carried his coffin in the town of Bani Walid, 146 kilometers (91 miles) southeast of the capital, Tripoli, as well as large photographs of both Seif al-Islam, who was known mostly by his first name, and his father.

Iran on Friday said it expected to hold more negotiations with the United States after a day of indirect talks in Oman seen as a critical chance for diplomacy after President Donald Trump threatened new military action against Tehran.

With an American naval group led by an aircraft carrier in Middle Eastern waters, U.S. and Iranian delegations held talks in Muscat mediated by the Gulf sultanate without publicly meeting face-to-face.

Iran and the United States will hold talks Friday in Oman, their latest over Tehran's nuclear program after Israel launched a 12-day war on the country in June and the Islamic Republic launched a bloody crackdown on nationwide protests.

U.S. President Donald Trump has kept up pressure on Iran, suggesting America could attack Iran over the killing of peaceful demonstrators or if Tehran launches mass executions over the protests. Meanwhile, Trump has pushed Iran's nuclear program back into the frame as well after the June war disrupted five rounds of talks held in Rome and Muscat, Oman, last year.

Iran's Revolutionary Guards have seized two oil tankers with their foreign crews in Gulf waters for "smuggling fuel," the Tasnim news agency reported Thursday.

It was not immediately clear what flags the tankers were carrying nor the nationalities of the crew.
