Note found in NYC attacker's truck

Two law enforcement officials say a note has been found inside the truck that barreled down a bike path near the World Trade Center in New York City, killing eight people.

One official says the note was hand-written in a foreign language, possibly Arabic. The contents are being investigated, but the officials say the document supports the belief the act was terrorism.

Police say the truck's driver turned onto the bike path Tuesday afternoon, striking several people before ploughing into a school bus.

Officials say he got out of the truck waving a pellet gun and a paint gun and was shot by a police officer. He's in critical condition after surgery.
