DOHA: Saudi Arabia's unexpected World Cup victory over giants Argentina triggered a rare moment of joint celebration across the fractured Arab world including among Qataris - less than two years after a seething regional dispute. A caravan of Qatari cars, horns honking, paraded through the streets of Doha after the Saudis' famous 2-1 win over the South American champions, one of the biggest upsets in World Cup history.

Such scenes would have been unthinkable during the nearly four-year, Saudi-led blockade that cut Qatar's diplomatic, trade and transport ties with its closest neighbors over disputed claims of supporting extremists and being too close to Iran. Complicated regional relations were forgotten as Tunisians, Moroccans, Egyptians, Lebanese and Jordanians joined the throng of Saudi fans that partied in the Qatari capital.

"This is a historic victory for Saudi Arabia and a great victory for all Arabs," 24-year-old Jordanian Ahmed Al-Qasim, his country's flag draped around his shoulders, told AFP at a Doha fan zone. The triumph was Saudi's biggest since its World Cup debut in 1994 and the first for a Middle Eastern country in this year's tournament, which is making its debut on Arab soil.

The outpouring of joy followed a series of bitter human rights disputes that drew angry responses from the Qatari organizers, including accusations of anti-Arab racism. Some Qatari fans raised the conservative kingdom's flag alongside their own, and even Qatar's Amir watched the game draped in a Saudi scarf - days after the Saudi Crown Prince donned Qatari colors.

"There was a political dispute between the two governments, but it has ended and at the end of the day, we are one people," said Anoud, a Qatari who asked to be identified only by her first name. "We have turned the page and the blockade is behind us," she told AFP outside a Doha shopping mall.

Tributes were paid around the region, with many Arab leaders voicing their congratulations on Twitter. Two Doha skyscrapers lit up their glass facades with the green colors of the Saudi flag, as did Dubai's Burj Khalifa, the world's tallest building. Celebrations were seen in Gaza and there were even fireworks in Yemen, whose powerful neighbor Saudi Arabia has led a military coalition since 2015 to prop up the internationally recognized government.

On social media networks, Saudi Arabia's victory topped regional trending lists and inspired a flurry of congratulatory posts as well as satirical memes mocking Argentina. Nevin Massad, a professor of political science at Cairo University, called Saudi's football win an "exceptionally emotional moment". "Political Arabism may no longer be possible, but there are different forms of Arabism among the people," including "an athletic Arabism", she told AFP.

Emirati political science professor Abdulkhaleq Abdulla called the Saudi team "Arab heroes", in a post on Twitter. Saudi Arabia's success was followed by creditable performances by Tunisia and Morocco, who fought out 0-0 draws with Denmark and Croatia respectively, both strong European teams. "We feel that all the Arabs are here behind us," said 23-year-old Saudi fan Khaled Abdullah, who was part of the celebrations in Doha. "Our joy is one." - AFP
