“Unknown hooded men wearing military uniforms attacked Mrs Bugaighis in her home and opened fire on her,” said a security official, who did not wish to be named.

She was shot several times and taken to hospital in critical condition, where she died shortly afterwards, a spokesman for the Benghazi medical centre said.
