UPDATE: A spokesman for STIB which is responsible for the Brussels Metro has announced that so far they believe that 15 people have been killed and 55 injured (of whom 10 are in a critical condition) following the explosion at the Maalbeek station. Local hospitals are appealing for blood donors to come forward.
French authorities have increased security in Paris and at their borders with Belgium whilst Paris Mayor Anna Hidalgo has announced that the Eifel Tour will be lit with the colours of the Belgium flag.
ABOUT 90 minutes after the explosions at Brussels airport, first details emerged of what could be a further bomb, this time at the Maalbeek metro station in central Brussels.
There is no further information available concerning casualties at the time of writing but it appears that the entire metro system has been shut down adding to the general confusion and fear that is afflicting the city.
Leaders from around the world, including David Cameron have sent messages of sympathy to the people of the city and expressed their horror at the events that are taking place there.
