Mexican authorities said on Tuesday they had fired the director of a prison near the US border where at least 30 inmates escaped at the weekend after a deadly riot, as police began a manhunt for missing convicts.
State prosecutors in the border state of Chihuahua said Alejandro Alvarado, head of the prison in the city of Ciudad Juarez, had been dismissed, and is also under investigation for his possible role in the jailbreak, alongside others.
On Sunday, 19 people died after gunmen attacked the prison a few miles south of El Paso, Texas, killing guards and inmates and triggering a mass escape that included cartel kingpin Ernesto Alfredo Pinon de la Cruz, also known as "El Neto".
Federal authorities arrived to restore order, later finding a "VIP zone" in the state-run prison with drugs and money.
Prisoners' relatives queued outside the prison on Tuesday, some asking to speak to authorities.
Maria Luisa Pena, an inmate's aunt, told Reuters authorities had yet to give her information about her nephew's situation.
"We're worried," she said, "We want to know what's happening with our relatives, we want them to tell us something."
"We're all humans, aren't we? We all make mistakes. Now many of us want the opportunity to know what's happening with our relatives," added an inmate's wife, who remained unidentified.
On Monday night, Chihuahua's government said seven people had died during subsequent police clashes as part of the hunt to find the escaped inmates. Two of the dead were police.
Sunday's incident resulted in one of the highest death tolls from prison violence in Mexico in recent years.
