French Foreign Minister Laurent Fabius said Friday that U.S. Secretary of State John Kerry had "apologized" for not attending a massive rally in Paris after a spate of Islamist attacks, alongside other world leaders.

Fabius and Kerry laid wreaths outside the Jewish supermarket and Charlie Hebdo offices targeted last week in deadly extremist attacks.
