A notorious gang in Haiti is slowly releasing hostages from a group of missionaries they kidnapped in mid-October, CNN reported. On Monday (Dec. 6), the Christian Aid Ministries revealed that three of their members returned after being released on Sunday (Dec. 5). The announcement comes after two hostages were let free last month. Twelve still remain in captivity.

“We are thankful to God that three more hostages were released last night,” they wrote in a statement. “Those who were released are safe and seem to be in good spirits. As with the previous release, we are not able to provide the names of the people released, the circumstances of the release, or any other details.”

The Christian group then asked supporters to fast and pray on Monday through Wednesday “to intercede for those who are still being held as well as those who have been released.”

As previously reported by REVOLT, the 400 Mawozo gang had captured 16 Americans and one Canadian in Port-au-Prince on Oct. 16 while they were working as missionaries. The group, which included an infant, two kids and two teenagers, visited an orphanage in Croix des Bouquets and were en route to Titanyen when they were kidnapped, prompting a message from the Christian Aid Ministries.

“Join us in praying for those who are being held hostage, the kidnappers, and the families, friends and churches of those affected,” the organization asked in the wake of the abductions. “We are seeking God’s direction for a resolution, and authorities are seeking ways to help.

According to Haitian Justice and Interior Minister Liszt Quitel, the leader of the gang previously demanded $1 million to release the captives; it is not clear whether any of the ransom money was paid.

Kidnappings conducted by 400 Mawozo and other gangs have reportedly spiked in Haiti, which is still attempting to recover from the assassination of late President Jovenel Moise and the aftermath of the 7.2 magnitude earthquake that hit the country in August.
