The widow of one of the six Britons killed during the siege of a gas plant in Algeria has said she still doesn't know how her husband Garry Barlow died.
Lorraine Barlow told BBC News: "Garry did not seem to receive any protection at all. Nobody came to his aid ... and I'd like to know why."
Mr Barlow, 49, from Liverpool, was working as a system supervisor at the In Amenas plant when it was attacked by several dozen gunmen. He phoned his wife to tell her that he had been taken hostage and made to wear an explosive vest.
Mrs Barlow also told the BBC she was shocked that BP - one of the plant's operators - had not invited her to a memorial service for staff killed in the attack.
BP said in a statement that Mr Barlow had been employed by an agency.
A memorial service for a former Norwich schoolboy killed in a terrorist attack in Algeria is to take place today.
26-year-old Sebastian John died in the attack at the In Amenas gas plant last month. He was an engineer who began work for BP last year and arrived in Algeria a week before the crisis.
The memorial service is due to take place at Norwich Cathedral this afternoon.
