US President Barack Obama says there is "no excuse" for criminal acts in Ferguson, Missouri, one night after two police officers at a protest were shot.

He said the protesters had "legitimate grievances" but described the shooters as "criminals" who should be arrested.

Wednesday's shootings happened during a demonstration after it was announced the Ferguson Police Chief would resign.

Further protests late on Thursday passed peacefully. The two officers have been released from hospital.
