General view of the National Assembly during a debate to extend a state of emergency, in Paris.

French lawmakers on Wednesday voted overwhelmingly to extend airstrikes against ISIS targets in Syria, which have been stepped up following the Paris attacks.

Paris has intensified its campaign against ISIS since the Nov. 13 Paris assaults that left 130 people dead, this week launching its first strikes from the Charles de Gaulle aircraft carrier in the Mediterranean.

The National Assembly approved a motion to prolong strikes by 515 votes to four, with 10 abstentions, as the defence minister said all 27 other European Union members had offered “direct or indirect” military support.

Prime Minister Manuel Valls told lawmakers again that France was “at war” with ISIS.

“There is no alternative: we must destroy Daesh,” Valls said, using an alternative name for ISIS.

He said French planes, which started hitting IS targets in Iraq in September 2014, had carried out more than 300 strikes against the extremists.

President Francois Hollande met his U.S. counterpart Barack Obama at the White House on Tuesday and German Chancellor Angela Merkel in Paris on Wednesday as part of a diplomatic push to forge a global coalition against ISIS.

Hollande’s efforts have so far produced only sketchy results — words of condolence from Obama but little in the way of firm commitments apart from an agreement to step up airstrikes on the extremists that U.S. jets have already been carrying out for months.

The French leader will be hoping for better results from his meeting with Merkel, his key EU ally.

Earlier Defence Minister Jean-Yves Le Drian said EU nations had rallied behind France.

“All 27 member states have agreed to support France — whether in the form of direct support in the Syrian theater, indirect support to our operations in the Levant, or indirect support in other theaters where French forces are engaged,” he said, without giving details of the support.
