Four Britons have been detained in Kenya on suspicion of terror offences after taking pictures in an airport, according to reports.
The men were arrested in Nairobi and taken for questioning after sparking the terror alert on March 12, The Sun said.
A Foreign Office spokesman said: "We are in contact with Kenyan authorities following the arrest of four British nationals and are ready to provide consular assistance."
The men, named as Ian Glover, 46, Steve Gibson, 60, Eddie Swift and Paul Abbott, both 47, are said to have been taking photos of planes taking off at Nairobi's Wilson Airport while they sat in a bar.
It is understood they thought they had been granted permission from airport officials, but were arrested by police.
The four appeared in court on Monday and were remanded in custody for a week charged with using a mobile phone app to monitor flights and trespassing, The Sun said.
Mr Swift's brother, Peter, told the newspaper: "Eddie and his mates are just chaps who like taking pictures of planes. It's a very worrying time."
He added: "It's blindingly obvious they weren't doing anyone any harm and weren't plotting anything. None of them would harm a fly."
