Primary school shooting leaves two adults dead and pupils hurt

An apparent murder-suicide inside a California primary school classroom has left two adults dead, including a teacher, and two pupils wounded, officials said.

Investigators believe “the suspect is down” and there is no further threat to North Park School in San Bernardino, Police Chief Jarrod Burguan said on Twitter.

Two pupilts were airlifted to hospital after what is believed to have been a domestic dispute, San Bernardino City Unified School District spokeswoman Maria Garcia told news station KNBC-TV.

Their conditions were not immediately known, police said.

“We believe the teacher knew who the shooter was,” Ms Garcia said.

She said all other pupils were safe and were being taken to a local college campus. Aerial footage showed students gathered on a field and a basketball court inside the fenced-in grounds of the campus as buses lined up.

Frantic parents ran up a pavement looking for information about their children but were not able to learn immediately what happened at the school. Several parents interviewed on TV said their children were too young to carry mobile phones, so they had not been able to contact them to see if they were safe.

The city was the site of a December 2015 terror attack that killed 14 people and wounded 22 at a meeting of San Bernardino County employees.

Husband-and-wife shooters Syed Rizwan Farook and Tashfeen Malik were killed in a gun battle with authorities.

The city is known for its high rates of violent crime, especially murders, and has struggled to emerge from bankruptcy.
