Marcus Fakana, 18 year old, jailed for a year in Dubai after 'holiday romance' with 17-year-old girl

Prosecutors say they acted on a complaint from the girl's mother - but campaigners have criticised the sentence and say the UK government hasn't done enough to help.

An 18-year-old Briton has been sentenced to a year in prison in Dubai after a "holiday romance" with a girl who was 17 at the time.

Marcus Fakana was with his family in the United Arab Emirates (UAE) when he met the girl - who's also from London and is now 18.

But with Moscow's drone and missile barrages into Ukraine growing in scale and regularity, Belarusian opposition groups say the danger to their country is increasing.

The Belarusian Hajun Project -- an open-source intelligence group banned as an "extremist" organization by Minsk -- said a record-high total of 151 drones entered Belarus during November. At least three were shot down by Belarusian air defenses, it added.

One Russian attack in late November saw a record 38 strike drones cross into Belarus, the group said. ABC News could not independently verify the drone flights.

The head of campaign group Detained In Dubai said his treatment was a "disgrace" and Mr Fakana felt abandoned by the British government since his arrest in September.

He's expected to appeal against the sentence.

Mr Fakana previously said the pair kept their romance secret from the girl's family "because they were strict" and had hoped to continue seeing each other back in the UK.

However, he said police turned up at his family's hotel and took him into custody without explanation.
