Experts from several countries and Interpol have joined Kenya's investigation into the four-day siege of the Westgate shopping centre in Nairobi by Islamist militants in which at least 67 people died. The Kenyan Interior Minister Joseph Ole Lenku confirmed that five militants believed to be from the Somali Islamist group al-Shabab had also been killed . From Nairobi Will Ross reports.

It's likely to be a slow process as forensic experts from Britain, America, Israel, Germany and Canada search for clues to reveal the identity and nationalities of the gunmen. The Kenyan government says their work has begun inside the battered and bloodied walls of the Westgate mall. Following the collapse of part of the building it's believed that there are still bodies under the rubble, possibly some of the militants. At other high-profile institutions in Nairobi also considered potential targets, security has been stepped up but much more is needed to ensure that another large-scale attack cannot happen here.

At least 24 people have died in the Sudanese capital Khartoum on the third day of demonstrations against cuts in fuel subsidies. The director of Omdurman hospital Dr. Osama Mortada told the BBC's Arabic Service they were treating many people the bullet wounds. “Until 8pm today, we have received about 81 injured people and we have 21 dead. All have gunshot wounds, some in the chest, some in the head while others have bullet wounds in their extremities. I believe it's all live ammunition. We have carried out more than 30 operations today.”

Earlier police fired teargas at stone-throwing demonstrators as riots broke out in parts of the capital.

Police in Athens have fired teargas to scatter protesters who'd gathered outside the headquarters of the far-right Golden Dawn party, a week after one of its members confessed to killing a left-wing musician Pavlos Fyssas. Mainstream parties had called for a large turnout to demonstrate support for democracy. Our Athens correspondent Mark Lowen was at the demonstration.

We were pushed back by the police upper of the headquarter Golden Dawn who used teargas against the crowds. It hits us at one point quite badly, we have to turn on our gas masks and we were pushed back and then the crowds sort of dispersed to different sites, there were petrol bombs and thrown at the police, couple of things are setting on fire, it's all crackdown, but certainly, the mood here was very much angry against Golden Dawn but also angry against the government because many here believed that the government has too long tolerated and even appeased the neo-Nazis.

The FBI says a former Navy reservist to shot dead 12 people inside a Naval complex in Washington last week believed he was a victim of mind control. An FBI spokeswoman Valerie Parlave told reporters that Aaron Alexis had carved a number of phrases into the side of a gun used in the attack.

“At this point, I can't confirm that there are multiple indicators that Alexis held a delusional belief that he was being controlled or influenced by extremely low frequency or electromagnetic waves. The etching of ‘ My ELF weapon’ on the left side of the receiver of the Remington 870 shotgun is believed to reference these electromagnetic waves.”

She said Mr. Alexis acted alone and there was no indication that he targeted any specific individuals when he opened fire in the Navy Yard where he was working as contractor.
