A power cut plunged several neighbourhoods of Brussels into darkness overnight after an unknown problem hit the grid, the Belgian capital's electricity distributor said Friday. "We are getting electricity again from (grid operator) Elia. We are gradually starting to restore the affected areas," Sibelga tweeted shortly after midnight. The power outage hit the neighbourhoods of Schaerbeek, Evere and Saint-Josse, in the northwest of the city, at 10.40 pm (2140 GMT), according to a Sibelga spokesman quoted by the Belga news agency. Five of the 48 high-voltage stations in Brussels were no longer powered by Elia, according to the spokesman.
