http://news.bbc.co.uk/2/hi/uk_news/8450603.stmStatement from Sunday Mirror editor Tina Weaver:“Rupert believed that the only place to report a war was from the front line, and as our defence correspondent he wanted to be embedded with the US marines at the start of their vital surge into Southern Afghanistan.
“He left on New Year’s Eve with photographer Phil Coburn, determined to be there from the start.He was a seasoned, highly-regarded and brave journalist who had reported from both Iraq and Afghanistan on many occasions.
“It was his fifth trip to Afghanistan, and he had forged friendships with a number of the soldiers serving out there.
“One of his last acts was to organise a special Christmas newspaper produced solely for the troops packed with messages from loved ones which was flown out by the RAF three weeks ago.
“He was a fine, fearless, and skilled writer who joined the paper 12 years ago.
“Affectionately known as Corporal Hamer in the office, he was a gregarious figure ,a wonderful friend who was hugely popular with his colleagues.
“Above all he was devoted to his wife Helen and their three young children.
“Our thoughts and condolences are with Helen, his father Nick, who he was so close to, and the children he was so proud of.”
“Phil is a veteran of conflicts in Iraq, Rwanda and Afghanistan who has been with the Sunday Mirror for eight years.
