France's final appeals court Wednesday cleared the extradition to Belgium of a French-Algerian man suspected of carrying out a deadly shooting at the Jewish Museum in Brussels.

The decision by the Cour de Cassation was no surprise as Mehdi Nemmouche, 29, had dropped an appeal against his extradition.

Belgium's King Philippe on Sunday urged his country's fractious politicians to form a national government as speedily as possible as negotiations drag on after May elections.

"You elected the men and women to represent you for the next five years on May 25," the king said in his first national day address since coming to the throne after his father, Albert II, abdicated in July 2013.

Former Ukraine president Viktor Yanukovych, ousted by pro-Western protests, has filed a suit with EU's top court against sanctions Brussels has imposed on him and two sons.

The European Court of Justice lists the Yanukovych suit along with cases made by several other prominent figures in the crisis, which was sparked when the former president ditched an EU Association Accord under intense pressure from Russia in November and eventually led to his ouster and the installment of a pro-Western team in Kiev.

A French-Algerian man suspected of carrying out a deadly shooting at the Jewish Museum in Brussels has dropped an appeal against his extradition to Belgium, his lawyer said on Friday.

Mehdi Nemmouche, 29, had filed an appeal against a June ruling that ordered his extradition from France, but his lawyer Apolin Pepiezep said he had decided not to go ahead with the challenge.

Gonzalo Higuain smashed home an early goal as Argentina dashed the World Cup dreams of much-fancied Belgium with a 1-0 win in the quarter-finals in Brasilia on Saturday.

Higuain struck in the eighth minute at the Mane Garrincha National Stadium to send Argentina into the last four for the first time since 1990 and thwart Belgian hopes of avenging their defeat in the 1986 semi-finals.

A French-Algerian man suspected of carrying out a deadly shooting at the Jewish Museum in Brussels is appealing a court decision to extradite him to Belgium, his lawyer said on Saturday. 

"Mehdi Nemmouche was informed of the decision of the court of appeal in Versailles on Thursday and he filed an appeal notice the same day," lawyer Apolin Pepiezep told Agence France Presse.

A French court on Thursday ordered the extradition to Belgium of a man suspected of carrying out a deadly shooting at the Jewish Museum in Brussels on May 24 that killed four people.

The court in Versailles, west of Paris, said Franco-Algerian Mehdi Nemmouche, 29, who was detained several days after the attack, should be handed over to Belgian authorities for "killings with a terrorist connotation."

Belgium risked plunging into a fresh political crisis after attempts to form a coalition government collapsed Wednesday amid allegations Flemish nationalists were not committed to keeping the country together.

Belgium's King Philip, who had tasked tough-talking Flemish nationalist Bart De Wever to try to put together a coalition government, "has discharged him from the mission," the palace said.

Teenage forward Divock Origi turned a listless Belgian performance into a late 1-0 win over Russia on Sunday, enough to qualify for the next round of the World Cup with two straight victories.

Belgium barely contained a reinvigorated Russia for most of the match, yet struck with a blistering final spurt of class and opportunism to turn a bad situation into a wild celebration for coach Marc Wilmots in the 88th minute and hugs all around at the fulltime.

Belgium's powerful Flemish separatists joined an anti-EU alliance on Thursday led by British Tories that may become the third biggest European Parliament group.

The Flemish N-VA, which in general elections held May 25 outstripped the country's other parties, won four seats to the next European Parliament at EU elections that took place the same day.
