Facing a nationwide surge in coronavirus cases fueled by the spread of the highly transmissible omicron variant, Abu Dhabi is requiring people entering the city to show proof of booster shots.

The government's health app said earlier this week that people entering the capital of the United Arab Emirates must show a "green pass," confirming their vaccination status. The app says that visitors are no longer considered fully vaccinated unless they have received a booster at least six months after their second dose.

Black-eyed Nirvana and Mr. Isa, two male camels from the western Aydin province of Turkey and wearing colorful saddles, circled the grounds with their owners and then wrestled fiercely as thousands cheered.

They were competing as part of 80 pairs or 160 camels in the Efes Selcuk Camel Wrestling Festival, the biggest and most prestigious festival of its kind, which celebrated its 40th run Sunday. The wrestling grounds is a few miles away from Ephesus, the site of ancient Greek ruins. Smaller festivals are held across Turkey's Aegean and Mediterranean provinces.

The mining encampment that stretches across a mountainside in Brazil's Amazon is dotted with plastic tarpaulin covers. Under them, dozens of men toil in rocky pits, excavating sacks of ore to be transported by truck. Gold will be extracted from the ore.

Of all places this squatter settlement shouldn't exist, it's here: in Brazil's northernmost Roraima state that doesn't permit gold prospecting, inside one of the nation's Indigenous reserves where mining activity is illegal and on the flanks of this mountain – Serra do Atola – that traditional leaders of the Macuxi people hold sacred.

Auction house Sotheby's Dubai has unveiled a diamond that's literally from out of this world.

Sotheby's calls the 555.55-carat black diamond — believed to have come from outer space — "The Enigma." The rare gem was shown off on Monday to journalists as part of a tour in Dubai and Los Angeles before it is due to be auctioned off in February in London.

An Israeli hospital has said preliminary research indicates a fourth dose of the coronavirus vaccine provides only limited defense against the omicron variant that is raging around the world.

Sheba Hospital last month began administering a fourth vaccine to more than 270 medical workers — 154 who received a Pfizer-BioNtech vaccine and 120 others who received Moderna's. All had previously been vaccinated three times with the Pfizer-BioNtech vaccine.

Satellite photos obtained by The Associated Press on Tuesday appear to show the aftermath of a fatal attack on an oil facility in the capital of the United Arab Emirates claimed by Yemen's Houthi rebels.

The images by Planet Labs PBC analyzed by the AP show smoke rising over an Abu Dhabi National Oil Co. fuel depot in the Mussafah neighborhood of Abu Dhabi on Monday. Another image taken shortly after appears to show scorch marks and white fire-suppressing foam deployed on the grounds of the depot.

Japan's government is preparing social restrictions in Tokyo and other regions as the omicron variant of the coronavirus infects more people.

Japan has never had a lockdown during the pandemic but has focused instead on asking restaurants and bars to close early. Crowds are back in many parts of Japan, with people packing stores and events, while COVID-19 cases jump.

South Korea's leader arrived in Saudi Arabia on Tuesday, where he was greeted in Riyadh by the kingdom's crown prince and an honor guard marching band.

It was the second stop on a Mideast tour by South Korean President Moon Jae-in and his wife, who were greeted on the tarmac by Crown Prince Mohammed bin Salman. All were masked and President Moon did not shake hands with the prince, in line with coronavirus social distancing practices.

British Prime Minister Boris Johnson on Tuesday denied misleading Parliament about lockdown-breaching parties, as senior government ministers said he would have to resign if he was proven to have lied.

Former Johnson aide Dominic Cummings has said he is willing to swear under oath that the prime minister was warned in advance that a May 2020 garden party for Downing Street staff would break coronavirus restrictions.

North Korea said Tuesday it had conducted a test-firing of "tactical guided missiles," a day after South Korea's military detected the North launching two ballistic missiles into the sea.

Monday's test was North Korea's fourth round of missile launches this month and the second since its Foreign Ministry warned of stronger and more explicit action after the Biden administration last week imposed fresh sanctions over the North's continued weapons displays.
