The first clues appeared in Kenya, Uganda and what is now South Sudan. A British arms researcher surveying ammunition used by government forces and civilian militias in 2006 found Kalashnikov rifle cartridges he had not seen before.
The ammunition bore no factory code, suggesting that its manufacturer hoped to avoid detection. Within two years other researchers were finding identical cartridges circulating through the ethnic violence in Darfur. Similar ammunition then turned up in 2009 in a stadium in Conakry, Guinea, where soldiers had fired on antigovernment protesters, killing more than 150.
British police say that Jimmy Savile, the late BBC star presenter, was a "predatory sex offender" whose victims were as young as eight years old, according to a newly released extensive report.
Savile preyed on children and adults in hospitals and even a hospice, according to the report, released by the police and child protection services on Friday. The television presenter was accused of having committed more than 200 sex crimes over more than half a century, from 1955 to 2009.
Police and child protection authorities found Savile used his celebrity status to "hide in plain sight", but that he could have been prosecuted. Police says the scale of Savile's sex abuse was "unprecedented in UK".
Syrian opposition fighters have overrun Taftanaz airbase, the largest in northern Syria, after several days of fierce combat, the Syrian Observatory for Human Rights has said.
Anti-government activists said fighters from Jabhat al-Nusra (al-Nusra Front) and other groups opposed to President Bashar al-Assad seized control of buildings, ammunition and military equipment in the sprawling Taftanaz airbase in northern Idlib province on Friday.
Addressing the issue of extremist safe haven in Pakistan requires more than a military solution, US President Barack Obama said today, noting that Islamabad has a crucial role to play in bringing peace and stability in Afghanistan.
"With respect to Pakistan and safe havens there, Afghanistan and the United States and Pakistan all have an interest in reducing the threat of extremism in some of these border regions between Afghanistan and Pakistan, and that's going to require more than simply military actions," Obama told reporters at a joint press conference with the visiting Afghan President, Hamid Karzai.
That's really going to require political and diplomatic work between Afghanistan and Pakistan; he said in response to a question from a visiting Afghan journalist when he asked the question of continued safe havens inside Afghanistan. The United States, obviously, will have an interest in facilitating and participating in cooperation between the two sovereign countries, he noted.
"But as President Karzai, I think, has indicated, it's very hard to imagine a stability and peace in the region if Pakistan and Afghanistan don't come to some basic agreement and understanding about the threat of extremism to both countries and both governments and both capitals.
"I think you're starting to see a greater awareness of that on the part of the Pakistani government," Obama said.
President Francois Hollande says French troops are taking part in operations against Islamists in northern Mali. French troops "have brought support this afternoon to Malian units to fight against terrorist elements", he said. Armed groups, some linked to Al Qaeda, took control of northern Mali in April.
Mr Hollande said the intervention complied with international law, and had been agreed with Malian President Dioncounda Traore. A state of emergency has been declared across the country.
US President Barack Obama and Afghan leader Hamid Karzai have discussed the possibility of keeping a US military force in Afghanistan beyond 2014.
In a joint statement after White House talks, the two leaders also said the US would give custody of Afghan prisoners to the Afghan government. They also backed holding talks in Doha between the Afghan government and the Taliban. They said "most" US combat operations would end by mid-2013.
