British Prime Minister David Cameron flew into the Libyan capital on Thursday for a previously unannounced visit, just days after Britain warned of threats to its embassy in Tripoli.Ringed by security, Cameron arrived at Tripoli airport at 11:00 am (1000 GMT).The British premier, accompanied by Libyan Interior Minister Ashur Shwayel, made his way to a police academy in southern Tripoli where he attended a ceremony to mark the promotion of officers.

A Libyan government official told AFP that security cooperation would be at the centre of Cameron’s talks in Tripoli.Downing Street said on Twitter that the prime minister travelled to the North Africa country “to discuss how the UK can continue to help build a strong, prosperous, democratic” Libya.The British embassy in Tripoli, for its part, tweeted that Cameron was in Libya “to reiterate UK support for Libya’s transition”. On Thursday, Britain urged its nationals to leave Benghazi immediately because of a “specific and imminent threat to Westerners” in the eastern Libyan city.

Several other Western nations followed Britain’s lead and advised their citizens to pull out, sparking anger from Libya which said the threat had been exaggerated. On Monday, Britain said it had also identified a “potential threat” to its embassy in Tripoli. Cameron paid a visit to Algeria on Wednesday tostrike a new security partnership between the two countries.His spokeswoman said before his departure that Cameron would seek a partnership with Algeria on tackling extremism, reflecting growing concern in London about unrest in North Africa, and in Mali.
