Two taxi drivers were murdered in Rosario this week. So far this year, four have been killed.

Despite the announcements, there is very little police presence and vehicle operations. "We are very vulnerable: you don't know who you are boarding as a passenger and you have them behind your back all the time," says Julián, a taxi driver from Rosario. It's a war between gangs, adds Horacio Yanotti, the secretary of the Rosario Taxi Workers Union.
