 I'm James Reynolds. You're listening to BBC OS Conversations on Hajj from the BBC World Service. And you may have been surprised, perhaps even shocked, to hear some of the behaviour encountered by the pilgrims at Hajj we spoke to. But of course, we mustn't forget that for millions of Muslims, it is an intensely positive experience. Saudi Arabia, for its part, will also point to the increased safety measures it has introduced in recent years.
