PARIS (AFP) - France's interior minister said he would host an international meeting Sunday for his counterparts from the United States and Europe to discuss the battle against terrorism in the wake of the Paris magazine massacre.

"I have taken the initiative of inviting to Paris on Sunday my counterparts from the most affected European countries... as well as my American colleague (Attorney-General) Eric Holder," said Mr Bernard Cazeneuve.

The meeting is about the other countries "showing their solidarity with France," which suffered its bloodiest attack in half a century on Wednesday when 12 people were mown down at the offices of satirical weekly Charlie Hebdo.

"But it's also about exchanging ideas about the common challenge that the terrorists are posing and which can only be resolved within the European Union and beyond," Mr Cazeneuve added.

A US Justice Department official said earlier Thursday that the meetings would include "discussions on addressing terrorist threats, foreign fighters and countering violent extremism."
