The body of a French tourist who was kidnapped and beheaded by jihadists in Algeria last September is to be flown home on Monday, a source close to the case told Agence France Presse.

DNA tests have confirmed that the headless corpse found in a booby-trapped grave in the mountainous Kabylie region, east of Algiers, on January 15 was that of Herve Gourdel, the source said on Sunday.

A father-of-three, suspected of bombarding his children with violent images glorifying jihad, has been charged with "inciting acts of terrorism", prosecutors in southeastern France said on Saturday. 

The man was also indicted for parental violence against minors under 15 and shirking legal obligations as a parent, the prosecutor's office in the town of Valence said.

Circulation of the "survivors'" issue of Charlie Hebdo, published after a deadly attack on the French satirical weekly's Paris office, is set to top seven million, the distributor said Friday.

A total of 6.3 million copies were for France alone, amid an outpouring of grief and anger over the attack by two Islamist gunmen this month which left 12 people dead, including some of Charlie Hebdo's top cartoonists. Five more people were killed in related attacks by a separate gunman.

Tens of thousands took to the streets in cities across Iran after Friday prayers to condemn French satirical magazine Charlie Hebdo for publishing a cartoon of the Prophet Mohammed.

The biggest demonstrations were in cities other than Tehran, with state television showing large crowds angered at the depiction of the prophet.

French President Francois Hollande will visit the typhoon-ravaged Philippines in February to build momentum for crucial climate change talks that France is hosting this year, his environment envoy said Friday.

Hollande hopes his visit would give a human face to climate change, as the Philippines bears the brunt of dozens of deadly storms every year, including the strongest on record, Super Typhoon Haiyan in November 2013, Nicolas Hulot told reporters.

Clashes between protesters and police erupted in Indian Kashmir's main city of Srinagar after Friday prayers amid a general shutdown called over the publication of cartoons of the Prophet Mohammed.

The closure of shops and businesses was ordered by a leading Muslim organization and several separatist groups to protest the "blasphemous" caricatures in the French satirical magazine Charlie Hebdo whose offices were attacked by Islamist gunmen on January 7.

France's top legal body ruled Friday that stripping a binational convicted jihadist of his French nationality was lawful, just as the country upped its fight against extremism.

The ruling by the Constitutional Council comes after the government announced a series of anti-terror measures in the wake of the deadly Paris attacks earlier this month and mulls whether to use this move more widely.

The number of anti-Muslim incidents in France has soared since the Paris attacks, with 128 such acts registered over two weeks, almost the same amount as all 2014, a watchdog said Friday.

The National Observatory Against Islamophobia said 33 acts against mosques in particular and 95 threats had been reported to authorities since the January 7-9 shooting spree by three French jihadists that killed 17, compared to a total of 133 such incidents in 2014.

France on Friday called for an immediate ceasefire in Ukraine's war-torn east, calling the upsurge  in fighting barely hours after peace talks in Berlin "dreadful".

"I renew a call in the firmest manner for a ceasefire... and to return to what we had agreed on yesterday," French Foreign Minister Laurent Fabius told AFP on the sidelines of the World Economic Forum in Davos.

French Prime Minister Manuel Valls created a stir on Thursday when he called for a "settlement policy" in France to fight against the "ghettoisation" of neighborhoods with strong immigrant populations.

Although many were left scratching their heads as to the exact meaning of the premier's words, it is not the first time that he has raised uncomfortable issues in the aftermath of the deadly Paris attacks earlier this month, determined to highlight inequalities in society he believes are partly to blame for the violence.
