Haitian gang leader says he will kill captive missionaries if he doesn't get what he wants

(CNN)The leader of the Haitian gang who kidnapped 17 US and Canadian missionaries has threatened to kill the hostages if he doesn't get what he's demanding, according to a video released Thursday.

The video was taken Wednesday at a funeral for gang members he alleges were killed at the hands of police, a Haitian security force source tells CNN.

The missionary group, which includes several children, has been held captive since Saturday. A spokesman for their organization, Christian Aid Ministries, declined to comment to CNN on the gang leader's remarks.

The missionaries was kidnapped over the weekend by the 400 Mawozo gang, while traveling by car northeast of capital city Port-au-Prince. Their captors have demanded $1 million per hostage, according to Haitian Justice and Interior Minister Liszt Quitel.

Among the kidnapped are an 8-month-old infant, a 3-year-old and a 6-year-old, as well as two young teenagers. All of the group's members hail from Amish, Mennonite and other conservative Anabaptist communities across six US states and Ontario, according to Weston Showalter, a Christian Aid Ministries official.

The threat follows the first public statement by the victims' families, who on Thursday thanked supporters and describing the kidnapping as a "unique opportunity" to show compassion.

"God has given our loved ones the unique opportunity to live out our Lord's command to love your enemies, bless them that curse you, do good to them that hate you," the families said in a message read outside of the Ohio headquarters of Christian Aid Ministries.

Quitel said Haitian police negotiators and the FBI are involved in helping to resolve the kidnapping, which has focused global attention on an epidemic of gang violence and insecurity in the impoverished Caribbean nation.

At least 782 people were kidnapped in Haiti between January 1 and October 16, according to the latest estimates by the Port-au-Prince organization Center for Analysis and Research for Human Rights (CARDH). At least 53 were foreign nationals.

Kidnappings for ransom have spiked in recent months following the assassination of Haiti's president in July, according to CARDH. At least 119 kidnappings were recorded in the first half of October alone, including 10 group kidnappings in just two days in the Port-au-Prince neighborhood of Martissant.
