ALGIERS - Algerian state energy company Sonatrach signed a deal on Thursday with France's Total to extend its supply of 2 million tonnes a year of liquefied natural gas (LNG) to the French market for another three years, it said.

Relations between Sonatrach and Total had deteriorated after Algeria blocked the sale of Anadarko assets to the French company, energy sources said.
