The biggest news stories rounded up in one place.

1. Charlie Hebdo shooting: more than 700,000 rally across France after deadly attacks.

More than 700,000 people took to streets across France in tribute to the 17 people killed in three days of violence by Islamist extremists, the interior minister said.

From Nice and Marseilles in the south to Besancon in the east and Lille in the north, people poured onto the streets to express their solidarity following Wednesday’s attack on the satirical weekly Charlie Hebdo that left 12 people dead.

The massacre was followed by the fatal shooting of a police officer on Thursday and the murder of four hostages during a siege at a Jewish supermarket on Friday.

“700,000 people have marched” in cities around France, Bernard Cazeneuve told reporters on the eve of a huge Paris rally planned due to be attended by a string of world leaders.

2. Most venues have now cancelled on anti-vax campaigner Sherri Tenpenny, leaving her tour in tatters.

Pressure is mounting against a planned speaking tour by American anti-vaccination campaigner Sherri Tenpenny, with nine of eleven venues now refusing to host her $200 per head seminar. The Sydney Morning Herald has described her tour as being “in tatters”

Dr Tenpenny, an osteopathic doctor who believes vaccines cause autism, asthma, ADHD and auto-immune disorders, is planning a series of lectures against vaccination in March aimed at parents of babies.

Tour organiser and anti-vaccination campaigner Stephanie Messenger told the SMH that the decision to cancel amounted to “bullying”.

Two venues, Michael’s Oriental Restaurant and Function Centre (an Asian restaurant in Brisbane) and Rydges Hotel in Adelaide, are still scheduled to host Ms Tenpenny’s talks.

“We’re monitoring it and haven’t made a decision one way or another,” a Rydges Hotel spokeswoman told the SMH. The Brisbane restaurant apparently did not respond to inquiries.

Mamamia and others have called on Immigration Minister Peter Dutton to deny the anti-vaccination campaigner a visa to speak in Australia. A spokesperson for Minister Dutton did not respond to Fairfax’s request for comment, but has previously indicated that the Minister is taking advice on the issue.

3. “Deadliest massacre in history”: 2000 people killed in Nigeria by Boko Haram says Amnesty International.

Too many bodies to count are apparently strewn in the Nigerian bush after an attack by Islamist extremists, Boko Haram, on the town of Baga. Amnesty International has said that the Nigerian town was razed and as many as 2,000 people killed.

A Nigerian government official told News Limited that insurgents attacked the town on January 3 and then again on Wednesday. In a statement, he said, “Security forces have responded rapidly, and have deployed significant military assets and conducted air strikes against militant targets”.

Reports indicate that most victims are “children, women and elderly people who could not run fast enough when insurgents drove into Baga, firing rocket-propelled grenades and assault rifles on town residents”.

The US State Department (the equivalent of Australia’s Department of Foreign Affairs and Trade), released a statement which said: “We urge Nigeria and its neighbours to take all possible steps to address the urgent threat of Boko Haram. Even in the face of these horrifying attacks, terrorist organisations like Boko Haram must not distract Nigeria from carrying out credible and peaceful elections.”

4. Sydney siege: Permanent memorial to honour Martin Place victims and heroes.

A permanent memorial to honour the victims and heroes of last month’s Martin Place siege will be built in Sydney, New South Wales Premier Mike Baird says.

Mr Baird said the memorial would honour the victims, hostages, police and emergency service workers caught up in the siege, which ended in the deaths of two people after more than a dozen were taken captive on December 15.

The memorial has not yet been designed, but will include a garden incorporating compost from the thousands of floral tributes left in Martin Place in the days after the siege.

A Martin Place Siege Memorial Committee, chaired by the Department of Premier and Cabinet, will develop the designs in consultation with the City of Sydney council, surviving hostages and the families of Tori Johnson and Katrina Dawson, who were killed in the siege.

Mr Baird said the memorial would be built by the first anniversary of the attack.
