Mexican authorities have recovered two bodies that match the description of the Colombian musicians reported missing a week ago in the country, the prosecutor's office in the state of Mexico said on Monday.

Forensic tests were underway to obtain official confirmation of the identities of the deceased, the prosecutor's office said.

Earlier on Monday, Mexican President Claudia Sheinbaum said that local authorities were investigating the whereabouts of reggaeton artist Bayron Sanchez, known as B-King, and Jorge Herrera, a DJ who performed under the name Regio Clown, after Colombian President Gustavo Petro requested Sheinbaum's aid in locating them.

In a social media post on Monday afternoon, Petro appeared to confirm the musicians' deaths by sharing a news article saying their bodies were found, blaming an "international mafia" that he said had been strengthened by the "war on drugs."

"More young people killed by an anti-drug policy that is not an anti-drug policy," Petro wrote.

On Sunday, the prosecutor's office in Mexico City, which borders the state of Mexico, said the two artists were last seen on September 16 in Polanco, a high-end neighbourhood in the Mexican capital.
