Sharjah 24 – AFP: US President Joe Biden on Wednesday kicked off a Middle East tour in Israel where both sides vowed to deepen the Jewish state's integration in the region as they face their common foe Iran.

Biden -- whose first regional visit since taking office will also bring him to Saudi Arabia -- pledged strong backing for Israel, which has forged ties with several Arab states in recent years and hopes to do so with Riyadh as well.

"We'll continue to advance Israel's integration into the region," Biden said after Air Force One touched down at Ben Gurion airport near Tel Aviv to a red-carpet welcome, while underscoring Washington's "bone deep" connection to the Jewish state.

"I'm proud to say that our relationship with the state of Israel is deeper and stronger in my view than it's ever been. With this visit, we're strengthening our connections even further," the president said.

Israel's caretaker prime minister Yair Lapid said that "we will discuss building a new security and economy architecture with the nations of the Middle East", following US-brokered accords in 2020 with the UAE, Bahrain and Morocco.

"And we will discuss the need to renew a strong global coalition that will stop the Iranian nuclear programme," he added, amid ongoing efforts by world powers to salvage Iran's frayed 2015 nuclear deal.

Biden's visit to Saudi Arabia on Friday is seen as part of efforts to stabilise oil markets rattled by the war in Ukraine, through a re-engagement with a long-time key US strategic ally and major energy supplier.

Air Force One will make a first direct flight from Israel to Saudi Arabia amid efforts to build ties between the Jewish state and the kingdom.

After Biden landed, Israel's military showed him its new Iron Beam defence system, an anti-drone laser it claims is crucial to countering Iran's fleet of unmanned aerial vehicles.

Israel insists it will do whatever is necessary to thwart Iran's nuclear ambitions, and remains staunchly opposed to a restoration of the 2015 deal that gave Tehran sanctions relief.

Biden, 79, will also meet Palestinian leaders angered by what they describe as Washington's failure to curb Israeli aggression.

The persistent frustrations of Israeli-Palestinian diplomacy are nothing new for Biden, who first visited the region in 1973 after being elected to the Senate.

In remarks to Israeli officials at the airport, Biden emphasised his continued backing for Palestinian statehood.

"A two-state solution," he said, remains "the best way to ensure" a prosperous future "for Israelis and Palestinians alike".

US-Palestinian ties have been strained by the May killing of Al Jazeera reporter Shireen Abu Akleh while she was covering an Israeli army raid in the West Bank.

The United Nations has concluded the Palestinian-American journalist was killed by Israeli fire. Washington has agreed this was likely, but also said there was no evidence the killing was intentional.
