Israel has unveiled its latest device to control protests on the West Bank and it is causing quite a stink, literally.

'Skunk' is a specially developed spray that drenches protestors with a foul-smelling liquid.

"It's very effective in preventing these demonstrations becoming lethal," police spokesman Micky Rosenfeld told Sky News.

"We don't want youngsters, children or anyone to become in a manner that is unnecessary."

For some reason, life as a foreign correspondent seems to expose you to more than your fair share of bad smells.

Without question, Skunk is one of the worst I have had to endure.

But it is not toxic, in fact it is organic. That is the clever bit.
