The hotel said in a statement: “Faena Hotel Buenos Aires is deeply saddened by the incident which took place in the vicinity of the hotel.

“We express our deepest condolences to the families and friends of the victims. Faena Hotel Buenos Aires is working with the authorities and providing our full support.”

Argentina’s newly elected president Alberto Fernandez said: “We must be tough. We can’t put up with this. We need to find the people responsible for this and make them pay with the full force of the law.

“It was an atrocious incident, like many that happen in Argentina, because criminality hasn’t gone down, despite what the official figures say.

“I urge everyone to stand up to it and be uncompromising when facing crime.”

More than 111,000 Britons visited Argentina last year and most visits were trouble-free, according to the FCO.
