Bodies found in search for Australian brothers and US man missing on Mexico surfing trip

Bodies have been found in the search for two Australian brothers and a US tourist who went missing in northern Mexico.

The remains were found south of Ensenada, near where the men - Jake and Callum Robinson from Australia and American Jack Carter Rhoad - went missing last weekend.

The trio, who were believed to have been on a camping and surfing trip, were only reported missing in the last few days - but the mother of the Robinsons said they hadn't been in touch since 27 April.

The location where the bodies were recovered, close to the town of Santo Tomas in Baja California state, is near where the men went missing, Mexican authorities said.

Their tents and truck were found on Thursday on a remote stretch of coast.

The bodies are yet to be formally identified.

Three people have been arrested and charged over the men's disappearance.

In a Facebook message, Jake and Callum's mother said she hadn't been in touch with her sons since 27 April and they had been travelling with "another friend, an American citizen".

The post, on 1 May, said they were meant to check into an Airbnb in the resort town of Rosarito after the weekend but "they did not show up".

She pleaded with the public to get in touch with any information, and added that Callum has Type 1 diabetes.

The US State Department said: "We are aware of those reports (of bodies) and are closely monitoring the situation. At this time we have no further comment."

Baja California prosecutors said on Friday that three people had been arrested and charged with a crime equivalent to kidnapping.

Maria Elena Andrade Ramirez, the chief state prosecutor, said evidence found with the abandoned tents was linked to the people being questioned.

While drug cartels are active in the area, she said "all lines of investigation are open at this time. We cannot rule anything out until we find them".
