Widow of Haiti's assassinated president returns to the country wearing her arm in a sling and a bulletproof vest

• Martine Moïse, the wife of Haiti's assassinated president, has returned to the Caribbean nation.
• She was pictured at Port-au-Prince airport on Saturday wearing an arm sling and a bulletproof vest.
• Moïse had returned to the country to prepare for her husband's funeral next week, an official said.

Martine Moïse, the wife of Haiti's assassinated president, returned to the Caribbean nation on Saturday after receiving medical treatment in Florida.

The widow was photographed arriving at Port-au-Prince airport with bodyguards, wearing an arm sling and a bulletproof vest. She was greeted by Haiti's interim Prime Minister, Claude Joseph, and other top officials.

Moïse was with her husband, Jovenel Moïse, on July 7 when a group of assassins broke into their private residence and killed him. She survived the attack but had to be flown to a hospital in Miami, Florida, for treatment.

In a tweet, a Haitian official said Moïse had returned to the country to prepare for her husband's funeral.

Her arrival was unannounced and surprised many in the impoverished country of more than 11 million people, who are still reeling from the assassination.

Last week, Moïse spoke from her hospital bed for the first time, saying in a voice message posted to Twitter that the attack happened so quickly her husband was unable to "say a single word."

"In the blink of an eye, the mercenaries entered my house and riddled my husband with bullets," Moïse said, according to the BBC.

Earlier this week, she tweeted: "The pain will never pass."

It is still unclear who exactly was behind the attack. Haitian police previously pointed to what it said was a group of assassins that includes 26 Colombians and two Haitian Americans.

Eighteen of those Colombians were detained, three were killed by the police, and five were still on the run, police said, according to Reuters.

This week, police took Jovenel Moïse's chief of security into custody - a decision that "came from above," CNN reported.

Jovenel Moïse's funeral is expected to happen next week.
