Paris  - French President Nicolas Sarkozy said on Wednesday it was essential that this week's G20 summit in London take concrete steps to sanction uncooperative tax havens.

"It is unacceptable and incomprehensible if concrete regulations cannot be applied in the coming days or weeks" to offshore tax havens that do not share information about their accounts, Sarkozy told Europe 1 radio.

Paris - French composer and three-time Oscar winner Maurice Jarre died at 84 after a battle with cancer, French media reported Monday.

Jarre died Sunday in Los Angeles, the reports said, citing Jarre's management.

The Lyon-born composer considered a pioneer of modern film scoring wrote the music for more than 150 films and was nominated nine times for Academy Awards, winning three for 1962's Lawrence of Arabia, 1965's Doctor Zhivago and 1984's A Passage to India.

Paris - When France is officially welcomed back to NATO's military command structure at the group's April 3-4 summit, it will restore what French President Nicolas Sarkozy suggested was normalcy to the country's relationship with the transatlantic alliance.
