All McDonald's outlets in Peru shut down for two days as a mark of respect for two of their colleagues who died at their outlet.
According to reports, the teenaged employees were electrocuted while cleaning the kitchen at a McDonald's branch in the capital Lima.
"In response to the terrible loss of our two colleagues Carlos Gabriel Edgardo Campos Zapata and Alexandra Antonella Porras Inga, we wish to announce that we have declared two days of mourning from this morning, during which all our restaurants nationwide will remain closed," the burger chain said on Twitter.
The firm, which has faced severe backlash over poor workplace safety, said it was cooperating fully with the authorities in the investigation.
