Fort Hood shooting: BBC reports from court

A former US Army psychiatrist who killed 13 soldiers at an Army base in Texas in 2009 has admitted in court he was the gunman and apologised for "any mistakes", as his court martial opened.

But Maj Nidal Hasan, 42, told the jury at Fort Hood, Texas, that the evidence told only one side of the story.

Maj Hasan has said he was protecting Muslims and the Taliban in Afghanistan.
