Bombs for brides: Islamic State dowries revealed in Libya

Forces allied with the country's unity government discovered the archives as they searched buildings seized during their months-long battle to oust IS from its coastal bastion of Sirte.

The documents belonged to the militants' "Judicial and Complaints Department".

Published on pro-government forces' Facebook pages, they include marriage contracts and divorce rulings without any real name or personal information. 

In one example from 31 November 2015, Abu Mansour, a Tunisian born in 1977, married a Nigerian called Miriam, in the presence of Sudanese and Malian witnesses. 

In contrast to Islamic norms, Abu Mansour did not pay a dowry but vowed to pay compensation in the event of his death or the marriage being dissolved - in the form of an explosive belt.

Fatima, from Nigeria, was promised a Kalashnikov assault rifle in case of divorce or if her husband, Malian Abu Said, died.

IS took over Sirte in June 2015 and began cracking down on any opposition, carrying out punishments including executions in public squares.

They patrolled the streets in 4x4s to ensure that men were observing prayer times and women were not venturing out alone. 

Forces allied with Libya's Government of National Accord launched an offensive on 12 May to retake the port city that was the hometown of late dictator Muammar Gaddafi.

They cornered the militants in a small area in central Sirte but were slowed down by snipers and suicide bombings that have killed some 450 pro-government fighters.
