The wedding at the prince's Aiglemont estate in the Oise department north of Paris was conducted by Dalil Boubakeur, rector
of the Paris mosque. The prince, 49th hereditary Imam of the Ismaili community was born in Geneva on December 13, 1936, son of Prince Aly Khan and Princess Joan Aly Khan.
The Ismaili community numbers 12 to 15 million people in 25 countries, the prince's office said.
Liningen, 35, comes from a family of industrialists. She has a six-year-old daughter from her first marriage.
Prince Karim, a graduate of Harvard University in the United States, has generally shunned publicity but is reputed to manage the same vast fortune his family has traditionally enjoyed.
He directs the Aga Khan Development Network which his office said was one of the world's largest private sector entities and is involved in health, education and rural projects.-Reuters
