FERGUSON, Mo. (AP) — St. Louis County Police Chief Jon Belmar says two officers were shot around midnight at a Ferguson, Missouri, protest.

He said a 32-year-old officer from Webster Groves was shot in the face and a 41-year-old officer from St. Louis County was shot in the shoulder.

He says both are conscious.

Belmar says he did not know who shot the officers.

The shots were fired as protesters had gathered following the resignation of Ferguson’s embattled Police Chief Thomas Jackson on Wednesday.

Jackson was the sixth employee to resign or be fired after a Justice Department report cleared a white former Ferguson police officer, Darren Wilson, of civil rights charges in the shooting of black 18-year-old Michael Brown in Ferguson last summer. Wilson has since resigned.
