PORTLAND, Maine (CNN) -- Hoping to elicit more information from the public, the FBI Thursday released new photographs of two of the suspected hijackers, taken from security cameras in the Portland area the day before last month's terrorist attacks.

The photographs showed Mohamed Atta and and Abdulaziz Alomari -- named by the Justice Department as two of the five hijackers on board American Airlines Flight 11, the first airliner that slammed into New York's World Trade Center -- at a Wal-Mart, gas station and ATM machine.

The FBI said the men were in Portland for a 12-hour period September 10. The next day, they boarded a flight to Boston, where they then got on Flight 11, authorities said. Previously released photos taken from a surveillance camera showed the men passing through a security checkpoint at the Portland airport.

An FBI agent said he hopes the new photographs would jog the memory of anyone who might have seen the men.

"We'd like to get more specifics about what they did and particularly who they talked to," said agent Charles Prouty, in charge of the FBI's Boston office.
