American President Joe Biden has urged Kenya to swiftly send its security forces to Haiti following the recent killing of three missionaries working with an American group in the strife-torn nation.

The call came on Friday shortly after the Haitian Missionary Society announced that its three missionaries were shot and killed by gunmen armed with rifles on Thursday night in the capital city of Port-au-Prince.

These killings are the latest in several months of escalating violence in Port-au-Prince, which is still controlled by persistent rebel groups that have carried out a series of deadly attacks across the city.

This plea also came as Kenyan President William Ruto concluded his visit to Washington, D.C., where he met with Biden and other top American leaders to discuss various issues, including the long-delayed operation to send forces to Haiti.

“The security situation in Haiti cannot wait,” said a spokesman for the National Security Council on Friday.

He stated that Biden pledged to support a “rapid deployment process” of forces led by Kenya during his talks with Ruto on Thursday. “We extend our condolences to the families of the victims during this time of mourning,” the spokesman said, referring to the missionaries.

Missouri State Representative Ben Baker revealed on Friday that his daughter, Natalie Lloyd, and her husband, Davy Lloyd, were among those killed.

The couple had been working as missionaries in the country, with Davy Lloyd being the son of the founders of the Haiti Mission Company, David and Alicia Lloyd, who established the organization in 2000.

The third person killed has not been identified.

The United Nations and other humanitarian aid organizations have been urging for more assistance to be provided to the people of Haiti.

Kenya has pledged to deploy 1,000 officers to participate in the largely U.S.-funded UN operation aimed at quelling rebel gangs.

The operation is expected to eventually involve 2,500 officers.

It remains unclear when the operation will begin after officials had initially stated it would be launched around the same time as President Ruto’s visit to America.

Unnamed sources reported on Thursday that the operation had been delayed.

Former U.S. Ambassador to Haiti, Daniel Foote, who has become a critic of the Biden administration’s policies, told the media last week that the intent of the operation was surrounded by controversy.

Many Haitians also question foreign intervention as past operations have failed to restore stability or address the country’s issues.

Recently, the UN peacekeeping force in Haiti was implicated in a severe cholera outbreak and allegations of sexual abuse.

Responding to a question about the Haiti deployment operation, Ruto said on Thursday that Kenya “believes the responsibility for peace and security anywhere in the world, including Haiti, is the duty of all nations.”
