Violent volcanic eruptions have significant impact on Tonga******

The eruptions of the Hunga Tonga-Hunga Ha'apai valcano in Tonga on Friday and Saturday have a significant impact on the South Pacific island country, especially its capital Nuku'alofa.。

According to Tonga's news website Matangi Tonga Online, Friday's violent volcanic eruption continued for over 12 hours and the volcano also erupted for eight minutes on Saturday, sending plumes of ash into the sky.。

The Royal Palace grounds, the waterfront and main street were flooded in Nuku'alofa, but information about the extent of damage in the island country is unavailable because its communication with the outside world has been cut off since Saturday evening as a result of the volcanic eruptions.。

According to Radio New Zealand, New Zealand Prime Minister Jacinda Ardern told a press conference Sunday afternoon that New Zealand High Commission in Nuku'alofa was in contact with local authorities and that damage assessments were underway.。

She said that the New Zealand High Commission said the tsunami waves had a significant impact on the foreshore on the northern side of Nuku'alofa, with boats and large boulders washed ashore. Shops along the coast were damaged, and there would be a need for a major cleanup.。

The undersea cable has been impacted, probably because of power cuts, and the Tongan authorities have been trying to restore communications, according to her.。

Ardern pledged that New Zealand will provide aid to Tonga and if necessary, New Zealand is ready to send planes and naval vessels. Reconnaissance flight will be useful in viewing the impact of the volcanic eruptions on the low-lying islands.。

Meanwhile, in Fiji, airborne ashes from Tonga are seen over the southernmost islands from Vatoa southward, with the ashes floating as far north as Tubou and Moala, and about to move to the island of Kadavu.。

Fiji's National Disaster Management Office (NDMO) said on Sunday that if the prevailing winds continue at the current level, airborne ashes could reach Fiji's central Lau and eastern Viti Levu, the major island of Fiji.。

The NDMO and the Fiji Meteorological Service have advised the people living on islands in the eastern area of the country to take necessary precautionary measures to avoid any exposure to the airborne volcanic ashes from Tonga.。

The Hunga Tonga-Hunga Ha'apai valcano, about 65km north of Nuku'alofa, is part of the highly active Tonga-Kermadec Islands volcanic arc, a subduction zone extending from New Zealand north-northeast to Fiji. Over the past decades, the volcano has erupted several times.。

Israel mulling 4th COVID******

AFP。

An expert panel of the Israeli Health Ministry on Tuesday recommended a fourth booster shot of the COVID-19 vaccine for those aged 60 and above amid concerns over the COVID-19 Omicron variant.。

The panel recommended the elderly receive a fourth shot at least four months after their third one.。

The recommendation is still pending the final approval of the ministry's senior health officials.。

Prime Minister Naftali Bennett welcomed the recommendation, saying he has instructed the country's four health maintenance organizations to start preparing for the fourth dose.。

"This is wonderful news that will assist us in getting through the Omicron wave that is engulfing the world," Bennett said in a statement.。

Health Minister Nitzan Horowitz wrote on Twitter that the administration of the fourth shot to the vulnerable group is "our top priority."

Israel has witnessed a flare-up of Omicron over the past few weeks.。

Bernabeu meeting to test Real Madrid and Sevilla's title credentials******

MADRID, Nov. 27 (Xinhua) -- La Liga leaders Real Madrid entertain third-placed Sevilla on Sunday night in a game that has a lot to say about both sides' title hopes.。

Real Madrid climbed to the top of the table last weekend after a 4-1 win in Granada, and a 3-0 victory in the Champions League away to Sheriff Tiraspol only served to confirm the good form of Carlo Ancelotti's men, with Vinicius Jr in the best form of his career and Toni Kroos also commanding in midfield.。

Ancelotti kept the pair on the pitch for the full 90 minutes in midweek along with Luka Modric and Karim Benzema, and one of the small doubts ahead of Sunday's game is whether or not they might start to feel tired, especially after also playing 90 minutes in Granada.。

Meanwhile, David Alaba, who has been excellent since joining from Bayern Munich in the summer, will miss the game with a minor knee injury, while Gareth Bale remains sidelined with a calf injury.。

Eden Hazard should be available after a bout of gastroenteritis, but the Belgian will once again have to settle for a place on the bench, while Nacho Fernandez is the natural replacement for Alaba alongside Eder Militao.。

Sevilla travel after a 2-0 win at home to Wolfsburg on Tuesday which kept their Champions League hopes alive, and the side coached by former Madrid boss Julen Lopetegui have had 24 hours more to prepare for the match.。

They are without injured striker Youssef En-Nesyri, but could start with the powerful Rafa Mir and the pacy Lucas Ocampos in attack.。

"It will be the first time I have played in the Bernabeu, I'm looking forward to it. Why can't we win there?" commented Mir in sports paper Diario AS.。

Lopetegui is likely to set his side out to contain Madrid, with midfielders Joan Jordan and Fernando sitting in front of the defense and looking for Ocamos and Acuna to try and hit their rivals on the break. A win for Sevilla could see them go top, while three points for Ancelotti's side would give them the chance to confirm their leadership and open a gap at the top if they can win at home to Athletic Bilbao on Wednesday.
