A stretch of sea wanted by Kenya and Somalia.
For years now, the two countries have been at loggerheads over a slice of the Indian Ocean, thought to be rich in oil and gas.
Both Kenya and Somalia desperately want it, but can’t quite agree on who actually owns it.
A case was filed with the International Court of Justice back in 2014.
After several delays, hearings are expected this week - though Kenya's announced it will not take part.
So, how did this dispute begin?
