SAN BERNARDINO, Calif. --Police say the attackers who killed 14 people at a banquet in Southern California had more than 1,600 bullets with them when they were gunned down in their SUV.

San Bernardino Police Chief Jarrod Burguan said at a news conference Thursday that the shooters had more than 3,000 rounds of ammunition at their home, 12 pipe bombs and hundreds of tools that could be used to make improvised explosive devices.

Authorities say Syed Farook and his wife or fiancee killed 14 people at the center Wednesday. The chief says the attackers fired between 65 and 75 rounds at the center. It is unclear if any one person was targeted. They later died in a gunbattle with police.

Burguan also says the number of people wounded in the mass shooting in Southern California has risen from 17 to 21.
