Twins Barbara (L) and Jenna Bush are holidaying in the country
One of the twin daughters of President George W Bush has been robbed of her handbag in Argentina despite protection by US Secret Service agents.
Barbara Bush, 24, lost her mobile phone and credit cards in the robbery in a restaurant in the capital, Buenos Aires - but she was not hurt.
She was dining with her twin sister Jenna at the time.
ABC News in the US says the robbery went unnoticed by the heavy secret service force protecting the family.
US officials in Buenos Aires and Washington have declined to comment on the incident.
The BBC's Daniel Schweimler in Buenos Aires says it is highly embarrassing for the protection force.
The Bush daughters have been on holiday in the city for the past three weeks.
Our correspondent says that although Buenos Aires, a popular tourist destination, remains one of the safest cities in Latin America, petty crime is on the increase - whether you are protected by the US Secret Service or not.
