Story highlights 57 officers, 12 protesters injured at Tel Aviv demonstration, police say

Anger in Israel's Ethiopian Jewish community reached a boiling point after viral video

Tel Aviv, Israel (CNN) A protest in Tel Aviv over alleged police mistreatment of Ethiopian Jews turned violent Sunday, resulting in 57 officers being injured, according to Israeli police.

Most of those injuries were minor, according to police, but one officer was described to be "moderately injured." Police say 12 protestors were injured. The extent of those injuries is not known.

The planned demonstration by the Ethiopian Jewish community -- incensed over a video gone viral that shows a uniformed Israel Defense Forces soldier of Ethiopian descent being assaulted by police -- had been peaceful for hours before things took a violent turn.

Authorities employed horses, water cannons and smoke to disperse the crowd in Rabin Square, where demonstrators had been chanting slogans such as "a violent cop should be in jail."

Forty-three protesters were arrested, according to Israeli police spokeswoman Luba Samri.
