SAN MATEO, Calif. (AP) - Officials say nearly 700 guns are off the streets of San Mateo County and are in the hands of law enforcement officials after the latest in a series of what authorities across the San Francisco Bay area have been describing as successful gun buyback programs.

San Mateo County sheriff's Det. Rebecca Rosenblatt, a spokeswoman for the department, says 680 guns - including 24 assault weapons - were turned in during Saturday's buyback held at the San Mateo Event Center.

In addition to the assault weapons, Rosenblatt says preliminary numbers show that 371 long guns or rifles and 285 hand guns were also turned over to officials.

In exchange for the guns, officials paid up to $100 in cash for a handgun, shotgun or rifle, and up to $200 for an assault rifle.

Officials say more than $63,000 in cash was paid out in exchange for the guns.
