A family member says a protester who was shot when snipers opened fire on police at a rally in Dallas was shielding her sons when she was injured.

A sister of 37-year-old Shetamia Taylor says Taylor was at the protests Thursday night with her four sons, ages 12 to 17. Theresa Williams says that when the shooting began, Taylor threw herself over her sons. She was undergoing surgery early Friday after being shot in the right calf.

Police say four police officers were killed and seven injured in the shootings. The shootings happened at a protest over recent fatal police shootings of black men.

Williams says two of Taylor's sons became separated from their mother in the chaotic aftermath. She says they're now stuck behind a police barricade at a hotel near a parking garage where police exchanged gunfire with a suspect.

A relative said Shetamia Taylor took her four sons, ages 12 to 17, to the rally and was wouned after throwing herself on top of them when the shooting began.
