Gaddafi troops 'linked to killings'

Retreating loyalists of Muammar Gaddafi killed scores of detainees and arbitrarily shot civilians over the past week, as rebel forces extended their control over the Libyan capital, survivors and a human rights group said.

In one case, Gaddafi fighters opened fire and hurled grenades at more than 120 civilians huddling in a hangar used as a makeshift lockup near a military base, said Mabrouk Abdullah, 45, who escaped with a bullet wound in his side.
