Here is a BBC report just 6 months old about foreign jihadists going to Somalia.

Somali Islamist insurgent group al-Shabab, which has joined al-Qaeda, has been pushed out of all of the main towns they once controlled in southern and central parts of the country but they still remain a potent threat to the UN-backed government.

Who are al-Shabab?

Al-Shabab means The Youth in Arabic. It emerged as the radical youth wing of Somalia's now-defunct Union of Islamic Courts in 2006, as it fought Ethiopian forces who had entered Somalia to back the weak interim government.

There are numerous reports of foreign jihadists going to Somalia to help al-Shabab

It has imposed a strict version of Sharia law in areas under its control, including stoning to death women accused of adultery and amputating the hands of thieves.
