The first known direct commercial flight between Israel and Bahrain has landed in the island kingdom, just a week after it signed a deal alongside the United Arab Emirates to normalise relations.

Flight data showed an Israir Airlines Airbus A320 landed at Bahrain International Airport after a nearly three-hour flight from Tel Aviv’s Ben-Gurion International Airport.

Hours later, Bahrain acknowledged the flight carried a delegation of Israeli officials.

“A working team from the state of Israel visited Manama today to discuss areas of co-operation between the two countries,” Bahrain said in a brief statement.

“These talks come after the signing of the Declaration of Peace.”

Bahrain did not identify the officials taking part, nor say who they spoke to while in Manama.

There was no immediate acknowledgement of the flight from the Israeli government, though Prime Minister Benjamin Netanyahu on Tuesday spoke by telephone to Bahrain’s Crown Prince Salman bin Hamad Al Khalifa.

Bahrain’s state-run media did not acknowledge the flight.

Officials on the island off the coast of Saudi Arabia did not immediately respond to requests for comment.

The US Embassy in Manama similarly did not respond to a request for comment.

The flight was made without ceremony, in sharp contrast to the first El Al flight from Israel to the United Arab Emirates at the end of August.

That plane carried US and Israeli officials, including President Donald Trump’s son-in-law Jared Kushner, as well as media.

In Bahrain, civil society groups have criticised the move to normalise relations with Israel, saying that recognition should come only after Palestinians obtain their own independent state.

Bahrain, home to the US Navy’s 5th Fleet and a British naval base, has a predominantly Shi’ite population ruled by a Sunni royal family.

Arab Spring protests there in 2011 ended with authorities cracking down with the help of Saudi and Emirati forces.

Bahrain and the UAE signed normalisation agreements on September 15 with Israel at the White House, part of a US diplomatic push as Donald Trump seeks re-election.

The UAE and Israel have moved quickly to explore commercial ties after their normalisation deal.

Bahrain’s King Hamad bin Isa Al Khalifa previously had been quoted as saying he believed Arab countries should drop their boycott of Israel.

It is likely Saudi Arabia, a major benefactor for his nation, gave its assent to the normalisation deal.

Wednesday’s Israir flight flew over the kingdom, which has opened its airspace to Israeli flights to both Bahrain and the UAE.

Kuwait’s ruler will travel to Washington on Monday for a working visit and hold talks with U.S. President Donald Trump, the state news agency KUNA announced on Sunday.

The White House said in a statement the leaders would discuss trade, investment and security cooperation in their Sept. 5 meeting.

Sheikh Sabah al-Ahmad al-Jaber al-Sabah has led mediation efforts to resolve a year-long dispute between Gulf Arab neighbours after Saudi Arabia, the United Arab Emirates, Bahrain and Egypt cut diplomatic, trade and transport ties with Qatar.

The four countries accuse Doha of supporting terrorism and cosying up to regional foe Iran. Doha denies those charges and says the boycott is an attempt to impinge on its sovereignty.

Trump publicly sided with the Saudis and Emiratis early on in the crisis but then began pushing for a resolution to restore Gulf unity and maintain a united front against Iran.

Reuters reported in July that the administration was quietly pushing ahead with a bid to create a new security and political alliance with six Gulf Arab states, Egypt and Jordan, in part to counter Iran’s expansion in the region, citing U.S. and Arab officials.

The administration’s hope is that the effort, tentatively known as the Middle East Strategic Alliance, might be discussed at a summit provisionally scheduled for Washington on Oct. 12-13, the sources said, though the Qatar rift could present a big obstacle.

Bahrain’s detention of activist Nabeel Rajab is unlawful and violates his right to freedom of expression, U.N. human rights experts have found, calling on the kingdom to release him immediately with compensation.

The government on Thursday rejected the findings of the U.N. Working Group on Arbitrary Detention, saying that Rajab’s offences did not relate to his political views and that his trials had been independent and transparent.

“As in all countries, there is a distinct difference between legitimate criticism of government and attempts to incite public disorder,” a government statement emailed to Reuters said.

Bahrain, where a Sunni Muslim royal family rules over a Shi’ite-majority population, has cracked down on perceived threats since Arab Spring protests in 2011, led mainly by Shi’ites, were quashed with the help of Gulf Arab neighbours.

Rajab was sentenced to five years in prison in February for criticising Saudi Arabia’s air strikes in Yemen and writing tweets accusing Bahrain’s prison authorities of torture.

A leading figure in the pro-democracy protests, he was already serving a two-year term over a news interview in which he said Bahrain tortured political prisoners.

In a formal opinion posted overnight, the U.N. panel of five independent experts said that provisions of Bahrain’s penal code were “so vague and overly broad” that people were punished for merely exercising their rights under international law.

“The Working Group therefore considers that Mr. Rajab’s deprivation of liberty is arbitrary,” it said, adding that: “no such trial” should have taken place.

Rajab’s political views were “clearly at the centre of the present case” and the government attitude had been “discriminatory”, it said. “He has been the target of persecution, including deprivation of liberty, for many years and there is no other explanation for this except that he is exercising his right to express such views and convictions.”

Rajab, held since June 2016, should be released immediately and compensated, it said.

The opinions of the panel are based on national obligations under international human rights law that they have ratified and are thus legally binding in nature, it says.
