CIUDAD JUAREZ, Mexico (AP) - Mexican Red Cross workers stopped treating gunshot victims for several hours in Ciudad Juarez.

That's after they received death threats over their two-way radios in the violent border city across the Rio Grande from El Paso, Texas.

Local Red Cross chief Jorge Diaz says two voices were heard over Red Cross radios Tuesday night threatening to kill emergency workers who cared for Juarez gunshot victims.

The Red Cross ordered its personnel to stop treating shooting victims while it decided on additional security measures. City government spokesman Jaime Torres says service resumed yesterday afternoon after police were sent to accompany ambulances.

Two months ago, the Red Cross was forced to restrict service in the city of 1.3 million residents that's home to the powerful Juarez drug cartel. The local Red Cross hospital stopped providing 24-hour emergency service after gunmen killed four people being treated for gunshot wounds. Emergency service there now ends at 10 p.m.
