MEXICO CITY, Aug. 3 (Xinhua) -- At least nine miners are believed to be trapped underground after a coal mine caved in in Mexico's northern Coahuila state, President Andres Manuel Lopez Obrador said Wednesday.
The collapse of the mine in the town of Sabinas caused a sinkhole to flood, presumably trapping the miners, Lopez Obrador tweeted.
"We hope to find them safe," he added.
Rescuers have rushed to the site and the investigation is underway. ■
