"Dissident republicans have been blamed for leaving a car containing a 400lb bomb outside the Policing Board's headquarters in Belfast.
The device in the car, which had been driven through a barrier by two men who then ran off, partially exploded at about 1900 GMT on Saturday.
Meanwhile, four men have been arrested following a gun attack on police officers in Garrison, County Fermanagh. "
