Egyptian warplanes have staged a second wave of air strikes against the Islamic State group in neighbouring Libya.

Egypt has launched air strikes against Islamic State (IS) targets in Libya after the extremist group released a grisly video showing a mass beheading of Coptic Christians held hostage for weeks.

Fighter jets dispatched by Libya’s internationally recognised government bombed a Greek-owned tanker ship at an eastern city controlled by Islamist extremists, killing two crew members and wounding two, Libyan and Greek officials said.
