Estimates of the number of foreign fighters in al-Shabaab vary widely, but a report released last year by the Royal United Services Institute suggested that about 50 Britons were believed to be fighting in Somalia.
Many are likely to be of Somali origin, but Muslim converts from some Western nations are believed to have links with al-Shabaab.
Last year intelligence experts warned that Britons were being recruited to fight for the militant group and that Somalia was becoming a vital training ground for British jihadis. Kenyan police believe Jermaine Grant, on trial in Mombasa on charges of possessing explosives, has links to the militants.
His accomplice Samantha Lewthwaite is on the run, with some reports suggesting that she has crossed into Somalia.
Lewthwaite, who faces the same charges as Grant, is the widow of the 7/7 King's Cross bomber Germaine Lindsay.
