An international anti-piracy force said Sunday it had captured nine Somali pirates suspected of two recent attacks in the Indian Ocean.

The Combined Maritime Forces -- naval patrols from 29 countries tasked with policing some of the world's most important shipping lanes -- said the pirates were picked up by Australian warship, HMAS Melbourne, some 500 nautical miles from the Somali coast.

At least 12 people died Saturday in a suicide attack in a restaurant in the central Somali town of Beledweyne claimed by the Shebab, witnesses said.

"It was horrible, I counted 12 people killed -- among them soldiers -- and many others were injured," Mohamed Islow Ali, a witness, told Agence France Presse by telephone.

Several prominent British Muslims said Friday that police have warned they may be in danger, after they were named as enemies of Islam in a video purportedly made by extremists linked to Somalia's Shebab militants.

London's Metropolitan Police said it was investigating the hour-long film, which was posted on YouTube on Wednesday but has since been removed.

A U.S. warship has rescued 128 migrants from an inflatable raft that was threatening to capsize in rough seas in the Mediterranean after a request from Malta, officials said Thursday.

The USS San Antonio, which is equipped with an amphibious transport dock that can help in rescue operations, was scrambled on Wednesday after a Maltese military aircraft spotted the dinghy.

One of Somalia's most notorious pirate leaders, known as "Big Mouth", is under arrest facing charges of kidnapping and piracy after being tricked into traveling to Belgium, the prosecution said Monday.

Federal prosecutor Johan Delmulle said Mohamed Abdi Hassan, known as "Afweyne" or "Big Mouth", was being held in Bruges after being detained at Brussels airport on Saturday on disembarking from a flight from Nairobi.

Two Somali nationals died when a bomb they were making detonated in their home in the Ethiopian capital Addis Ababa, as thousands gathered to watch a football match, officials said Monday.

"The ones who died were of Somali origin," Ethiopia's Minister of Information Redwan Hussein told AFP.

The African Union (AU) on Friday endorsed a move to boost its Somalia force by 35 percent to step up its fight against al-Qaida-linked Shebab rebels.

The AU mission in Somalia (AMISOM) will be boosted by 6,235 troops, taking the total number to 23,966, the AU's Peace and Security Council said in a statement.

Somalia said Sunday it was "not a secret" it is working with foreign governments to fight terror and described the country's al-Qaida-linked Shebab militants as a threat to the world.

Prime Minister Abdi Farah Shirdon was commenting after U.S. commandos launched a raid against Shebab militants in Somalia, in tandem with a strike against a wanted al-Qaida leader in Libya.

Turkey denied Sunday that its forces were involved in an assault in Somalia by U.S. commandos against a suspected military leader of the Islamist Shebab group.

"We deny these allegations completely," a foreign ministry spokesman told AFP.

U.S. forces struck two militant targets in Africa on Saturday, snatching a top Al-Qaida suspect from the streets of Tripoli and launching a pre-dawn raid against a Shebab leader's home in Somalia.

In Libya, US forces seized a militant known as Abu Anas al-Libi, a long-sought Al-Qaida operative indicted in the 1998 bombings of U.S. embassies in Kenya and Tanzania.
