Many people gathered for funerals held today in Paris and Jerusalem to remember the police officers and hostages at a kosher deli killed in last week's terrorist attacks in France.
Meanwhile, authorities continue to investigate the motives of the attacks.
Chérif and Saïd Kouachi and Amediy Coulibaly are believed to be responsible and the men claimed they had links to Al Qaeda in the Arabian Peninsula and the so-called Islamic State.
Frank Gardner, BBC security corespondent in London, discusses the ongoing investigations with Here & Now's Robin Young.
