Wednesday's blast came as French President Emmanuel Macron attended a WWI memorial ceremony in Paris

Jeddah: Several people were wounded Wednesday in a bomb attack at a World War I commemoration ceremony attended by European diplomats at a non-Muslim cemetery in Jeddah, Saudi Arabia, France's foreign ministry said.

"The annual ceremony commemorating the end of World War I at the non-Muslim cemetery in Jeddah, attended by several consulates, including that of France, was the target of an IED attack this morning, which injured several people," the ministry said.

"France strongly condemns this cowardly, unjustifiable attack."

Last month, a Saudi citizen with a knife injured a guard at the French consulate in Jeddah on the same day that a knife-wielding man killed three people in a church in Nice in southern France.

Wednesday's blast came as French President Emmanuel Macron, the target of ire in much of the Muslim world for vowing to confront Islamist radicalism following a spate of attacks, attended a WWI memorial ceremony in Paris.

Several countries are marking the 102nd anniversary of the armistice signed by Germany and Allied countries to end the war.

Macron has vigorously defended the right to publish cartoons viewed as offensive by some, including caricatures of the Prophet Mohammed printed by satirical magazine Charlie Hebdo.

The same cartoons were shown by French history teacher Samuel Paty to pupils in a class on free speech, leading to his beheading outside Paris on October 16 following an online campaign by parents angry over his choice of lesson material.

Macron's stance angered many Muslims, prompting protests in several countries at which portraits of the French president were burnt, and a campaign to boycott French products.

Saudi Arabia -- home to Islam's holiest sites -- has criticised the cartoons, but "strongly" condemned last month's attack in Nice.

On Tuesday, Macron hosted a summit of European leaders to plot a joint approach to combating Islamist radicalism after four people were killed in a shooting rampage in the heart of Vienna last week.
