PARIS (AP) — There are fears in France that the two heavily-armed brothers who are suspected in yesterday's massacre at the offices of a Paris newspaper might strike again.

One of the men, Cherif Kouachi (sheh-REEF' koo-AH'-shee), was convicted of terrorism in 2008 because of ties to a network sending radical fighters to Iraq.

His lawyer confirms that police tracked down the identities of the brothers because one of them left his ID behind in a getaway car.

Authorities are focusing their search around two towns northeast of Paris.

Two men resembling the suspects robbed a gas station in northeast France this morning.
