Paris  - If Myanmar's authorities continue to lag in cooperating with foreign aid agencies, France will take the case to the UN Security Council, French Foreign Minister Bernard Kouchner said Wednesday.

"We will have to see if we cannot force the (Myanmar) government to allow aid workers into the country," Kouchner told journalists in Paris.

He made his comments after meeting German Development Minister Heidemarie Wieczorek-Zeul.

Wieczorek-Zeul said that Cyclone Nargis, which killed at least 22,000 people in Myanmar, was the worst catastrophe since the tsunami of 2004.

"Our appeal is: open the country for aid workers so that the people can have a future," Wieczorek-Zeul said.

Both minister said that two United Nations airplanes carrying aid have received permission to land in the badly damaged port city of Yangon.

"That is not the air bridge that we need, but it's a first step," Kouchner said. (dpa)
