Said, the elder of the Kouachi brothers, has been to Yemen, a French official said. There, he had weapons training with al Qaeda, a U.S. official with access to French intelligence said.

His younger brother, Cherif, was sentenced to three years in prison for being part of a jihadist recruitment ring in Paris that sent fighters to join the conflict in Iraq.

An ISIS radio broadcast Thursday praised the attackers, calling them "brave jihadists." But the broadcast did not say whether the two had any connection to the militant group.
