BELFAST, Northern Ireland, Nov. 22 (UPI) -- Two men crashed a car carrying a 400-pound bomb through barriers at Belfast police headquarters but it only partially exploded, authorities said Sunday.
The Police Service of Northern Ireland said in a statement the men fled the vehicle after driving it through the barriers Saturday night but only a small explosion followed about 30 minutes later, CNN reported.
"Had this device functioned as the terrorists planned, there would have been widespread damage and destruction," the statement said.
The statement did not mention any injuries in the incident, CNN said.
Police said a nearby car fire set soon after the incident was suspected to be linked to the car bombing. Police appealed to anyone who may have witnessed the car fire to come forward.
Four men suspected of plotting a "terrorist attack" were arrested Saturday in a separate case in Garrison, County Fermanagh, police said.
