Prosecutors in Haiti say they are investigating Prime Minister Ariel Henry in connection with the assassination of President Jovenel Moise in July.
Henry was named prime minister by Moise shortly before the president was shot dead at his home. Henry took office after the assassination, and is currently leading the nation on an interim basis.
Prosecutors said on Tuesday they asked authorities to ban Henry from leaving the country, citing his possible involvement in the case.
They said phone records show Henry spoke with a key suspect in the president's killing twice just hours after the incident. Henry, in a Twitter post, denied involvement in the killing.
On Tuesday, Henry indicated in Twitter that he is committed to the country's recovery from a strong earthquake that struck August 14, leaving more than 2,000 people dead.
Observers say, however, that the latest developments in the murder investigation may cause political uncertainty and hamper reconstruction efforts.
