A person has been killed at the Qatar Embassy in Paris and one person has been arrested as part of the investigation, the Paris prosecutor’s office said on Monday, confirming earlier media reports.

“I can confirm that an investigation was opened today on the count of murder,” the prosecutor’s office said, adding that it was not clear yet if a weapon had been used.

“The circumstances of the death of the guard are yet to be determined precisely.”

Newspaper Le Parisien said earlier on Monday that one person had been killed within the embassy, citing police sources. (Reporting by Tassilo Hummel and Juliette Jabkhiro; Editing by Sudip Kar-Gupta and Ingrid Melander)
