Danish police have arrested two brothers suspected of plotting a terrorist attack.

The men are Somali Immigrants who have lived in Denmark for 16 years.

The men are 18 and 23 years old and were arrested after they were overheard talking about attack methods, targets and weapons types.

The 23-year-old had been at a training camp in Somalia run by the Islamist militant group al-Shabab, which has links to al-Qaeda.

The Danish government says the men are the first known terror-trained suspects in Denmark.
