(CNN)A Mexican journalist was shot Monday as he was about to go live on air and died in hospital later the same day.
Israel Vázquez, who worked for digital news outlet El Salmantino, was covering a "discovery of human remains" in the city of Salamanca, in the central state of Guanajuato, at the time of the attack, according to a tweet from the state's attorney general's office.
A special team is investigating the 31-year-old journalist's death, said the attorney general. No arrests have been made so far.
El Salmantino released a statement on Facebook urging a swift investigation.
"Today our colleague, Israel Vázquez, while working as a reporter, was the target of a vile and cowardly attack that took his life," read the statement. "All of us who work at El Salmantino condemn not just this one attack, but all of those that occur daily in the city of Salamanca."
Diego Sinhue Rodríguez Vallejo, governor of Guanajuato, condemned the death of Vázquez on Twitter, as did the municipal government of Salamanca, which tweeted a statement making an "urgent call to action" from the attorney general and the state government.
Vázquez is the third journalist killed in Mexico in less than a month, according to the Committee to Protect of Journalists (CPJ), which ranks the country as the deadliest in the world for the profession.
Two reporters covering protests in the city of Cancun, Quintana Roo state, late Monday local time were treated for gunshot wounds, tweeted the CPJ. At least two more reporters were beaten by police, added the organization.
Last year, CPJ reported that 11 journalists were killed in Mexico, the highest worldwide, outpacing war-ravaged Syria, where seven journalists were murdered in 2019.
Nine journalists have been killed in Mexico so far this year, tweeted Reporters Without Borders.
