The EU said Wednesday it is moving this week's leaders' summit out of its new 320-million-euro headquarters into a neighbouring building after chemical fumes from the kitchen sickened several people.

"In the light of today's incident in the Europa building, it has been decided, as a precautionary measure, that the European Council of 19-20 October will take place in the Justus Lipsius building," the European Council said in a statement.
