An armed gang, 400 Mawozo, kidnapped 17 members of an Ohio-based Christian missionary organization in Haiti on Saturday. Five of the hostages are children, including an 8-month-old. The group is seeking a ransom of $1 million per person for their safe release, the Haitian justice minister told The Washington Post on Tuesday.

The kidnapping of the 16 Americans and one Canadian has brought renewed attention to the United States’ long-standing no-concessions policy in hostage situations — while some other countries take a sharply different approach.

Between 2001 and 2017, nearly 1,200 Westerners from 32 countries were taken hostage by terrorist, militant and pirate groups. About one-fifth of those hostages were Americans — 41 of whom were killed by their captors, according to a report published by the public policy think tank New America.

Here is how the United States and other countries manage their hostage policies.
