British Foreign Secretary Philip Hammond and U.S. Secretary of State John Kerry will host a meeting in London of members of the coalition against the Islamic State (IS) militant group on January 22.
Officials said on January 17 the one-day meeting would involve foreign ministers from some 20 countries, including Arab states.
Hammond told the Daily Telegraph newspaper the meeting would "be an important opportunity to take stock and assess the progress made so far in our joint efforts to tackle [the IS's] poisonous ideology."
Hammond said it was "vital that we consider what more we can all do to tackle the issue of foreign fighters, to clamp down on ISIL's financing, to step up humanitarian assistance and continue our coordinated military campaign."
The announcement of the meeting comes after U.S. President Barack Obama and British Prime Minister David Cameron met in Washington earlier this week.
