(BBC) French President Nicolas Sarkozy has told the US Congress it can count on France's support against terrorism in Afghanistan and Iran's nuclear plan.
He received a standing ovation during the first address by a French president to both houses in more than a decade.
He also urged Americans to do more in the fight against global warming.
The French leader, who is on his first official visit to Washington, later met President George W Bush for talks at Mount Vernon, near Washington.
They are expected to discuss Iraq, Iran and other Middle Eastern issues.
