Journalist shot dead in Northern Ireland rioting

A year after moving to Londonderry, celebrated young Northern Ireland journalist Lyra McKee wrote about how she looked forward to "better times ahead and saying goodbye to bombs and bullets once and for all".

On Thursday night - just three months later - the 29-year-old McKee's final Twitter post showed a police vehicle being pelted by petrol bombs with the caption: "Derry tonight. Absolute madness."

She was killed shortly afterwards, shot dead by a gunman firing towards police during a riot that underscored the challenges still faced by Northern Ireland, a British province, 21 years after the Good Friday Agreement largely ended decades of deadly sectarian bloodshed.
