OAKLAND, Calif. (AP) -- A student wounded in a California college shooting rampage described chaos in the Oakland classroom where a gunman burst in shouting and quickly began firing his weapon.

Ahmad Sayeed, who transferred to Oikos University in March, was shot through the shoulder as he scrambled to get out of the room with other panicked students.

The 36-year-old immigrant from Afghanistan says he did not understand what the gunman was yelling, though he did hear him order students to line up in front of the classroom.

As some began to comply, gunfire erupted and students began screaming and fleeing the classroom.

Sayeed and three other students locked themselves in an empty classroom as the gunman moved to the hallway. He said he didn't realize until later that he had been wounded and was bleeding.
