The Archbishop of Canterbury has said the Church of England accepting gay marriage could be "catastrophic" for Christians in other parts of the world.

The Most Rev Justin Welby told LBC Radio in London that hundreds of Christians in Africa had been killed by people who associated Christianity with homosexuality.

He warned the same could happen if the Church of England backed gay unions.
