Reinhard Bonnke: Evangelist who drew millions in Africa dies at 79

German evangelist Reinhard Bonnke, who drew huge crowds in Africa over decades of preaching, has died aged 79.

"He passed away peacefully, surrounded by his family," his wife Anni Bonnke said in a statement.

The family lives in the United States but Bonnke was best-known for his work with the Christ For All Nations organisation throughout Africa.

The Pentecostal preacher oversaw more than 79 million conversions to Christianity, his organisation claims.

"It's no exaggeration to say that his work transformed the continent," it said in a statement.

At huge rallies - including one in Lagos, Nigeria in 2000 that was said to have drawn 1.6 million people - Bonnke claimed to heal people using the powers of God. He also told followers he had witnessed resurrections.

Nigerian President Muhammadu Buhari paid tribute to the evangelist, saying his death was a "great loss to Nigeria, Africa and [the] entire world".

Bonnke was born in 1940 in Königsberg, Germany. The city on the Baltic Sea is now called Kaliningrad, and is part of Russia.

He became involved in missionary work in Africa at a very young age and in 1974 founded the Christ For All Nations mission organisation, which was headquartered in South Africa and later in Germany.

Bonnke's held a farewell gospel campaign in 2017 in Nigeria, after which he stepped down as the organisation's leader due to health issues.

His activities in Africa at times stirred controversy.

In 1991, there were religious riots in the Nigerian city of Kaduna after police granted permission for Bonnke to hold a revival meeting and thousands of Muslims took to the streets in uproar. At least eight people were reported killed.

In 1999, 16 people died in a stampede during a rally organised by Bonnke in Benin City, Nigeria.

In 2014, the Associated Press reported that he was living in a $3m (£2.3m) apartment near Palm Beach, Florida.
