Gaz de France Workers Against Merger with Suez

Gaz de France workers opposed to its planned merger with Suez SA seized control of two liquefied natural gas import terminals and eight gas storage terminals this morning, the Confederation Generale du Travail said.

The Rough gas storage facility, the nation's largest, remains shut until at least May 1, cutting supplies about 10%.

National Grid Plc, manager of the U.K. pipeline network, issued the so-called gas-balancing alert for the first time since it started the system last year.
