Several European Union countries will sign an agreement on Monday to team up to buy artillery rounds for Ukraine as part of an effort to speed up and increase the supply of shells that Kyiv says it urgently needs to fight Russia's invasion.
A senior EU official said many of the bloc's 27 countries were expected to sign the so-called project arrangement, which sets out the terms of reference for the plan, but the precise number was unclear as some were still examining the proposal.
