This posting is liable to be updated as more information comes in.  01.27am.

Information is beginning to stream in of a car bomb attack on Palace Barracks, one of the largest British Army bases in Northern Ireland, and the NI headquarters of MI5.  Update: Confirmed by @eamonnmallie 12.20am explosion at rear of barracks.

Unconfirmed reports suggest additional attacks at Shankhill Road Police Station and Loughshore Army Depot.  All these locations are deep inside unionist areas of Northern Ireland.  The blast(s) take place on the morning when Policing and Justice powers are to be devolved in Northern Ireland.

As ever, hopes the morons behind these nonsensical terrorist attacks are brought to justice, and hopes that nobody has been injured or too seriously inconvenienced by the actions of these unthinking cretins.
