French police were still hunting on Thursday night for two brothers suspected of being behind the lethal attack on a satirical magazine after a possible sighting in a forested area northeast of Paris earlier in the day.
The two suspects were identified by police on Wednesday evening as Said and Cherif Kouachi, aged 34 and 32, French nationals of Algerian descent.
Said Kouachi travelled to Yemen in 2011 and may have received training from an al-Qaeda group, a US official said on Thursday. Mr Kouachi spent several weeks in Yemen where he may have been trained at a camp run by al-Qaeda in the Arabian Peninsula (AQAP), the terror group’s Yemen-based affiliate.
