RAF jets were among Nato forces which struck a command and control centre where Libyan leader Colonel Muammar Gaddafi sometimes lives.

The alliance said the dictator was not a target and there was no way of knowing whether he was there at the time of the raid.
RAF Typhoons were among the aircraft that used precision guided weapons in Libya to bring down guard towers along the walls of the Bab Al Aziziyah complex in the centre of Tripoli in the early hours.
The Chief of Defence Staff's spokesman, Major General John Lorimer, said: "For decades, Colonel Gaddafi has hidden from the Libyan people behind these walls, spreading terror and crushing opposition.
"The massive compound has not just been his home but is also a major military barracks and headquarters and lies at the heart of his network of secret police and intelligence agencies.
"Last night's action sends a powerful message to the regime's leadership and to those involved in delivering Colonel Gaddafi's attacks on civilians that they are no longer hidden away from the Libyan people behind high walls."
