One of the men suspected of carrying out the Westgate shopping centre attack in Kenya last month has been identified as a 23-year-old Norwegian citizen. The BBC has been told that the investigators believe Hassan Abdi Dhuhulow is one of four gunmen seen on CCTV footage inside the mall. Gabriel Gatehouse reports.

Until now, little was known about the four attacker seen on CCTV footage during the siege of Westgate. Investigators knew them by the colour of their clothes, they dubbed them black shirt, white shirt, blue shirt and pink shirt. But now sources close to the investigation in Kenya and in Norway have told the BBC they believed the man identified as a black shirt is Hassan Abdi Dhuhulow. Mr. Dhuhulow fled Somalia with his family in 1999, he returned to Mogadishu ten years later and since then, the family member said, he'd been in only sporadic contact.

Security has been increased in Uganda after the United States warned about the possibility of a Westgate-style attack in Kampala. Both Uganda and Kenya have sent troops to Somalia to help a UN backed government which is fighting al-Shabab.

President Barack Obama has said the US budget row and partial government shutdown inflicted unnecessary damage on the American economy. He was speaking hours after signing legislation to reopen the government.

Some of the same folks who pushed for the shutdown and threatened default claimed their actions were needed to get America back on the right track, to make sure we're strong. But probably nothing has done more damage to America's credibility in the world, our standing with other countries, than the spectacle that we've seen these past several weeks. It's encouraged our enemies, it's emboldened our competitors, and it's depressed our friends who looked to us for steady leadership.
