Attack on ex-Libya rebel HQ kills 28

At least 28 people were killed and 60 were wounded on Saturday when demonstrators attacked the headquarters in Benghazi of former rebels who had fought to oust Libyan dictator Muammar Gaddafi, a hospital official said.
Fighting erupted after dozens of demonstrators, some of them armed, tried to dislodge the powerful "Shield of Libya" brigade from its barracks in Benghazi, said an AFP correspondent at the scene.
They encircled the headquarters and called on regular security forces to step in.
Libya's post-Gaddafi authorities, who have still not managed to form a professional new army and police corps, often call on the "Shield of Libya" to intervene in the various tribal conflicts that trouble the country.
Adel Tarhuni, spokesman for the Shield of Libya group, said one member of the brigade had died and another seven were wounded.
Tarhuni also defended the "legitimacy" of the brigade, saying it officially came under the umbrella of the defence ministry.
