BUENOS AIRES, Argentina – Here's the latest on the Group of 20 summit (all times local):

10:05 a.m.

The European Union wants world leaders to use a summit in Argentina to confront the Saudi crown prince over threats to journalists and the Russian president over his country's actions in Ukraine.

EU Council President Donald Tusk spoke Friday at the Group of 20 summit and called on fellow leaders to discuss "trade wars, the tragic situation in Syria and Yemen and Russian aggression in Ukraine."

He didn't mention the killing of Saudi journalist Jamal Khashoggi, but stressed the importance of the "basic safety of journalists" and said "it's our obligation to press our partners to respect these basic principles."

There are deep divisions among G-20 leaders and Tusk acknowledged that "this is a difficult moment for international cooperation."

The summit opens Friday in Buenos Aires.

9:55 a.m.

European Council President Donald Tusk says the EU is expected to extend sanctions on Russia over its "totally unacceptable" seizure of Ukrainian ships and their crews near Crimea.

Tusk said Friday that "Europe is united in its support for Ukraine's sovereignty and territorial integrity" and called the standoff "a cause of great concern."

Tusk was speaking on the sidelines of a G-20 summit in Buenos Aires and he urged the leaders meeting to use the summit to discuss points of tension including what he called "Russian aggression in Ukraine."

Russian President Vladimir Putin is among the leaders involved. Russia and Ukraine have traded blame over the ship incident.

9:45 a.m.

Diplomats from the G-20 countries are haggling hard over a final summit statement, with deep divisions over what language to use on the Paris climate accord and the World Trade Organization, according to two European officials involved in the discussions.

Facing the prospect of a no-statement summit, European delegations are trying to create a common front and may come out with their own separate declaration if they can't get the U.S. or others on board.

European leaders are meeting Friday morning at the summit venue to stake out common positions on trade, climate and the killing of Saudi writer Jamal Khashoggi.

France is seeking to build coalitions on certain issues or "ad hoc partnerships" to try to salvage the spirit of the G-20 even if all countries can't agree, according to a French official.

The officials weren't authorized to be named speaking about the closed-door discussions and spoke on condition of anonymity.

9:05 a.m.

Russian President Vladimir Putin has arrived in Argentina's capital for the Group of 20 summit, where a highly anticipated meeting with U.S. President Donald Trump was abruptly called off.

Putin's plane landed Friday morning in Buenos Aires and he was greeted by officials on the tarmac.

Trump tweeted on Thursday that he was canceling the one-on-one with Putin because of Russia's seizure of Ukrainian vessels near the Crimean Peninsula, which Moscow annexed in 2014.

A Putin spokesman said the cancellation meant the Russian president would have more time for "useful meetings."

7:55 a.m.

German Chancellor Angela Merkel still plans on meeting Russian President Vladimir Putin for talks on the sidelines of the Group of 20 summit in Argentina despite her delayed arrival.

Merkel's arriving later than intended because a technical issue with her government plane forced her to change plans, but spokeswoman Martina Fietz said Friday she'll still meet one-on-one with Putin on Saturday morning.

On Thursday, Merkel said she hoped to use the meeting to press Putin to deescalate tensions with Ukraine over the Russian seizure of three Ukrainian ships in the Sea of Azov.

Germany's calling for the ships and sailors to be released, and is trying to help bring about a diplomatic solution to the crisis.

6:50 a.m.

German Chancellor Angela Merkel is finally on her way to Argentina for the Group of 20 summit after a technical problem with her plane forced her to change plans and stay overnight in Bonn.

Merkel's office says she and a small delegation, including the finance minister, took a different government plane to Madrid on Friday morning, and then boarded a commercial flight to Buenos Aires.

Merkel was en route Thursday night on an air force plane, but turned around over the Netherlands after the captain reported a technical problem.

The plane was diverted to the Cologne/Bonn airport and landed without incident.

The problem is being investigated but the air force says it appears to have been an electrical issue that could have affected the radio system and a fuel system.

2 a.m.

Leaders from the world's leading economies were invited to the Group of 20 summit to discuss development, infrastructure and investment. As the gathering officially kicks off Friday, those themes seem like afterthoughts, overshadowed by contentious matters from the U.S.-China trade dispute to the conflict over Ukraine.

Also expected to loom large are tensions between longtime allies the United States and Europe, the gruesome slaying of a dissident Saudi journalist and how the Saudi crown prince who is alleged to have ordered the killing is received by world leaders.

The U.S., Canada and Mexico also are supposed to sign a trade deal replacing the North American Free Trade Agreement that was struck following months of tough negotiations that analysts say left a bitter taste among the partners.
