A major church group in Sweden is planning to use drones to drop thousands of electronic Bibles over parts of Iraq controlled by the Islamic State.

"The Bibles are the size of pill boxes and have a display," Christian Akerhielm from the Livets Ord group said in an interview with SVT. "They require no electricity, but work on their own."

On its website, the church group added: "Our ambition is to pass on the hope and love that can fit in the Christian gospel to a population living in closed areas where human rights are denied."

"We start our project in a few weeks and hope to drop thousands of Bibles," the group added online.

The mission will be completed by another organization on Livets Ord's behalf, which will be using drones to drop the devices.

Livets Ord was founded in 1983 and has similarities to the United States' Pentecostal movement. It has sent missionaries to numerous countries in the past, including Russia, Afghanistan, Israel and India.
