Security tightened as Libya celebrates two years since revolt
Borders have been closed and some international flights suspended amid fears of a new outbreak of violence.

Security forces were on high alert across Libya on Sunday as the north African nation marks two years since the start of the revolt that toppled Muammar Gaddafi after four decades of iron-fisted rule.
Borders have been closed and some international flights suspended amid fears of a new outbreak of violence.
The anniversary of the uprising that ended with Gaddafi’s killing in October 2011 comes as Libya’s new rulers battle critics calling for a “new revolution” and accusing them of failing to usher in much-needed reforms.
On Friday, thousands of people gathered in the main cities of Tripoli and Benghazi to celebrate the initial February 15, 2011 protest that ignited the revolt two days later.
There is no official programme for Sunday’s anniversary, but the authorities have taken steps aimed at preventing any violence on a day when spontaneous celebrations are expected.
