Officials from more than 20 countries, including Israel —but no Arab states— will convene in Paris tomorrow to define a strategy on how to curb financing of Hamas and its activities online, three diplomats said, Reuters reports.

French diplomats have said they want a broader strategy encompassing as many countries as possible, to damage the group’s ability to finance itself and disseminate propaganda on social media networks.

The one-day conference of foreign ministry political directors will begin with a presentation by Israel on the “state of Hamas’ threat” before turning to sessions on curbing financing, according to an agenda seen by Reuters.

“It’s odd that there won’t be any Arab countries,” said one diplomat, whose country has been invited. Two other diplomats also confirmed the absence of Arab countries and Turkey.
