 The US state department has condemned a Pakistani minister's offer of $100,000 (£61,600) for the death of the American maker of an anti-Islam film. 
 
 It said the step was "inflammatory and inappropriate". 
 
 Railways Minister Ghulam Ahmad Bilour made the offer after a wave of protests against the film across Pakistan and the wider Muslim world. 
 
 Dozens have died in clashes between police and protesters in Pakistan and countries such as Tunisia and Sudan. 
 
 Sunday saw a fresh round of protests over the film in Pakistan, Nigeria, Greece and Turkey. 
 
 Most passed off peacefully, but in the Greek capital Athens, riot police and demonstrators clashed. Six people were arrested. 
 
 A state department official told the BBC: "The president and secretary of state have both said the video at the core of this is offensive, disgusting, and reprehensible - but that is no justification for violence, and it is important for responsible leaders to stand up and speak out against violence. 
 
 "Therefore we find Mr Bilour's announcement is inflammatory and inappropriate. We note that the prime minister's office has dissociated itself from his comments." 
 
 In hiding 
 
 The exact origins of Innocence of Muslims, the low-budget film that has prompted the unrest, are unclear. 
 
 The alleged producer of the trailer of the film, Nakoula Basseley Nakoula, is in hiding. 
 
 Anti-US sentiment grew after a trailer for the film dubbed into Arabic was released on YouTube earlier this month. 
 
 US citizens have been urged not to travel to Pakistan, and the US embassy has paid for adverts on Pakistani TV showing President Barack Obama and Secretary of State Hillary Clinton condemning the film. 
 
 Although US targets have borne the brunt of protests against the film, anti-Western sentiment has been stoked further by caricatures of the Prophet Muhammad published this week in the satirical French magazine, Charlie Hebdo.

 An 18-year-old man who threatened the magazine's editors on Facebook has been charged with terrorism-related activity following his arrest in the southern French city of Toulon, a judicial source told AFP news agency on Sunday. ||||| Islamabad, Pakistan (CNN) -- A Pakistan government minister has personally offered a $100,000 reward for anyone who kills the man who made the anti-Islam movie that is drawing ire throughout the Muslim world. 
 
 Railway Minister Ghulam Ahmad Bilour announced the bounty at a news conference Saturday, but he made clear to CNN he was speaking for himself and not as a government representative. 
 
 Asked whether he was concerned about committing or condoning a crime as a government official, Bilour said, "I am a Muslim first, then a government representative."

 He said he invited the Taliban and al Qaeda to carry out the assassination. 
 
 Sen. Zahid Khan, a spokesman for Bilour's political party, said the minister's action is not representative of the Awami National Party. 
 
 "We believe in nonviolence. How could we make such announcements?" Khan said. "Our party has been fighting against militancy and extremism for years. How could we invite Taliban and al Qaeda to kill someone? Taliban and al Qaeda are our enemies who have killed our loved ones." 
 
 "We have lots of concerns over the statement of our colleague," he added. 
 
 The leftist Awami National Party is a coalition partner in the federal government led by President's Asif Ali Zardari's Pakistan People's Party. The ANP is a ruling party in northwestern province of Khyber Pakhtunkhwa.

 Prime Minister Raja Pervez Ashraf condemns the bounty issued by Bilour, his spokesman said Sunday. 
 
 Shafqat Jalil said the prime minister will take up the issue with the head of the Awami National Party. 
 
 Bilour did not mention the filmmaker by name, but he was likely referring to Nakoula Basseley Nakoula, the man who U.S. officials say is behind the privately produced film. 
 
 Nakoula and his family have already left their California home and gone into hiding amid the worldwide storm of protest, the Los Angeles County Sheriff's Department announced.

– A US official has called it "inflammatory and inappropriate" for a Pakistani minister to offer a $100,000 bounty for killing the filmmaker of Innocence of Muslims. Railways Minister Ghulam Ahmad Bilour, who made the offer, said he would pay the bounty out of his own pocket as protests continued yesterday against the anti-Islamic film. Bilour, who called himself a "Muslim first and a government representative second," said he has invited the Taliban and al-Qaeda to carry out the assassination, reports CNN. Pakistani government officials have similarly blasted the offer. A US State Department official told the BBC yesterday: "The president and secretary of state have both said the video at the core of this is offensive, disgusting, and reprehensible—but that is no justification for violence, and it is important for responsible leaders to stand up and speak out against violence." In another threat, this one aimed at the French publication Charlie Hebdo for printing cartoons of the prophet Mohammed, an 18-year-old man who threatened the magazine's editors on Facebook has been charged with terrorism-related activity.
