Haiti's unelected Prime Minister Ariel Henry reportedly resigns
Mr Henry is currently stranded in Puerto Rico after being prevented by armed gangs from returning home.
US Secretary of State Blinken committed a further $100m (£78m) to the 1,000-strong UN-backed security force Kenya is expected to lead in Haiti.
The proposed US contribution to the security force now stands at $300m following Mr Blinken’s announcement, with a further $33m allocated for humanitarian aid.
The Caricom group of Caribbean leaders, alongside the US and representatives from Haiti, also discussed the framework of the political transition.
The council has been mandated to “swiftly” appoint an interim prime minister, he said, adding that anyone intending to run in Haiti’s next elections will not be able to participate.
