A security guard was killed in the early hours of Monday inside the Qatar Embassy in Paris in an incident that does not appear to have any links to terrorism, a source close to the investigation said.
The incident took place at around 0630 (0430 GMT), the source said, adding that the suspect had entered the embassy and had a row with the security guard, who died after being punched.
The Paris prosecutor's office confirmed the death and said one person had been arrested on the spot.
