US Secretary of State John Kerry has arrived in Paris ahead of Monday’s international conference on battling militant group Islamic State (ISIL).
Nearly 40 nations have so far agreed to contribute to what Kerry said would be a worldwide fight to defeat the militants.
Kerry flew to Paris from Cairo where he met the Egyptian president and foreign minister.
Egypt’s strong public support for Kerry’s campaign contrasts with a mixed response from elsewhere in the region.
ISIL militants have carried out mass killings of Sunnis, Shi’ites, Christians, Yazidis and Kurds.
Governments fear their own citizens who fight for the militants could return and threaten national security.
The US-led coalition will carry out a potentially complex military campaign to defeat the jihadists.
