On Monday European stocks retreated for a fourth day, the longest losing streak in almost three weeks, amid growing concern the economy is weakening. Asian shares declined while U.S. index futures were little changed.

Air France-KLM Group and Deutsche Lufthansa AG, Europe’s biggest airlines, fell more than 1 percent after a trade group cut the industry’s profit forecast.

The Stoxx Europe 600 Index slid 0.3 percent on course for the lowest close since March 22.

But traders said there was a lot more detail and legislation to go through until the situation was resolved and there were still worries over other peripheral euro zone countries.

Japanese stocks slid to the lowest level since March, as slowing U.S. jobs growth fueled concern the global economy is weakening and Tokyo Electric Power Co. plunged to a record low. Tokyo Electric, operator of the nuclear plant crippled by the March 11 earthquake and tsunami, plunged 28 percent after a report that Tokyo Stock Exchange President Atsushi Saito said the power company should be put in bankruptcy protection.
