SAN DIEGO - US police “neutralised” a shooter at a mosque complex in California on May 18, after a large number of emergency vehicles surrounded the sprawling Islamic Center of San Diego.

TV footage from a helicopter showed armed response teams gathered outside a building, with one unidentified person lying in a pool of blood.

CNN reported one security guard had been killed, citing the mosque official.

“The threat at the Islamic centre has been neutralised,” San Diego police said on X.

Imam Taha Hassane said in a video clip that there were some unconfirmed casualties – without giving details – but all the students at the complex’s school were safe.

“We are safe. The entire school is safe. All the kids, all the staff and the teachers are safe,” he said.

“We have few casualties – not confirmed yet.

“There is no threat at this moment, but we want everyone to stay away,” he said. “Stay safe, stay at home, and make a lot of prayers.”
