DUBAI, United Arab Emiratesinfo-icon-- Israelinfo-icon's figurehead president arrived in the United Arab Emirates on Sunday in the first official visit by the country's head of state, the latest sign of deepening ties between the two nations as tensions rise in the region.

The UAEinfo-icon and Israel normalized relations in the fall of 2020, part of a series of U.S.-brokered diplomatic deals between Israel and Arab states that had long avoided formal relations with Israel over its decades-old conflictinfo-icon with the Palestinians.

The office of President Isaac Herzog said he would be meeting top officials including Abu Dhabiinfo-icon's powerful Crown Prince Sheikh Mohammed bin Zayed Al Nahyan, the de facto Emirati leader, along with members of the country's small but growing Jewish expat community. He also was expected to visit Expo 2020, the worldinfo-icon's fair in Dubai, where Israel has hosted a series of events at its national pavilion.

Upon landing in Abu Dhabi, Herzog was greeted with a warm handshake by Emirati Foreign Minister Sheikh Abdullah bin Zayed Al Nahyan. They then held talks in the royal palace.

The president plays a largely ceremonial role as a national unifier in Israel's parliamentary system, where the prime minister holds the most power. Israeli Prime Minister Naftali Bennett last month made his first official visit to the Gulf Arab sheikhdom and discussed strengthening relations on a number of fronts with Sheikh Mohammed.

Shortly before takeoff, Herzog said he sought to bring on his visit "the message of peace from Israel to the United Arab Emirates, and to all the peoples in the region."

The show of Israel-Emirati cooperation comes at a delicate time for the Middle Eastinfo-icon.

Fighting in Yemeninfo-icon's seven-year civil warinfo-icon has intensified, widening to reach Emirati soil for the first time this month. The Iraninfo-icon-backed Houthi rebels fighting the Saudi-led coalition claimed aerial attacks against Abu Dhabi - one that killed three workers at an industrial area and another that was intercepted and scattered missileinfo-icon shards over the capital.

The assaults shocked residents, puncturing the sense of safety pervasive in the region's globalized businessinfo-icon hub. The Houthis have threatened further strikes this week.

Meanwhile, negotiations in Vienna between world powers and Iran to curb Tehraninfo-icon's rapidly expanding nuclear program paused on Friday, with European officials saying the talks had approached "the final stage." Former President Donald Trumpinfo-icon pulled the U.S. out of the landmark nuclear deal nearly four years ago in a move welcomed by Israel and Americainfo-icon's Gulf Arab allies and reimposed harsh sanctions on Iran.

Shared enmity of Iran and mutual fears over its nuclear program helped push the UAE and Israel to formalize relations after years of clandestine ties.

Palestinian leaders have condemned the normalization deal as a betrayal of their cause for statehood.
