Britain has put expats working in Nigeria on the alert in the face of the recent upsurge in terrorist attacks and kidnapping in the country.

The British Foreign and Commonwealth Office announced that the threat from terrorism is running high in the country and red-zoned many areas for expats to stay away from.

“Attacks can literally happen anywhere although major towns and cities in the north of the country are most at risk,” said an FCO spokesman, adding:

“The help we can give expats or tourists is limited and all but essential travel to some areas should be cancelled.”

“Particular danger spots are public places such as religious gatherings, markets, public transport stops and petrol stations.

“Kidnap is also a risk, mainly for ransom. Not only terrorists but criminal gangs are striking all over the country.”
