BBC News staff gathered outside Broadcasting House in London today, on World Press Freedom Day, to pay their respects to a BBC reporter and nine other journalists killed in the field this week.

BBC Afghan reporter Ahmad Shah was shot dead by unknown gunmen on Monday in the country’s Khost region, aged 29. The same day, a suicide bomber disguised as a press cameraman killed nine journalists in Kabul.

In a statement, BBC News director Francesca Unsworth (pictured, centre) said: “We are still trying to come to terms with the loss of a journalist who, like the others who died on Monday, was simply doing his job.
