Charlie Hebdo shooters were 'cold-blood murderers', says terror expert

Hooded gunmen who stormed the Paris offices of a weekly satirical magazine were well-trained "cold-blood murderers," a terror expert said on Wednesday.

The suspected Islamists shot dead at least 12 people, including two police officers, in the worst militant attack on French soil in decades.

One of the assailants was captured on video outside the building shouting "Allahu Akbar!" (God is Greatest) as shots rang out. Another walked over to a police officer lying wounded on the street and shot him point-blank with an assault rifle, before the two calmly climbed into a black car and drove off.

"They are cold-blood murderers," said Co-Director at the European Strategic Intelligence and Security Center in Brussels, Claude Moniquet.

"They took the time to wound the policeman and after they achieve (reach) him they kill him on the ground because this man was just wounded. He had an arm (weapon), of course, he's a policeman so he was still dangerous. And they knew they had to kill him to perform the attack. They demonstrated perfect cold-blood, perfect calm for all the operation and they killed at least twelve people and wounded ten others in just one or two minutes. So that tells us that they are clearly well-trained people and very decided people," he said.
