The drug war has hit a stomach-churning new low in Mexico. Up to twelve gunmen stormed into a drug rehabilitation clinic in the border city of Juarez, lined up patients against a wall and executed them at point blank range.

The concrete floor of the center for drug addicts was drenched in blood. Relatives of those killed and injured rushed to the scene. Most were told their loved ones had been murdered.

There is nowhere, it seems, in Juarez where the turf war for control of the drug market is not fought. Dealers chase down potential rivals into the corridors of these rehab centers. They indiscriminately fire at everyone there in the hope they kill off one or two enemies.

I spoke to the mayor of Juarez like at the IDesk last Monday. The federal government may have deployed thousands of troops to help pacify this urban killing field, but Mayor Jose Reyes Ferris told me more help was needed. The United States, a few hundred meters from Juarez, needed to do more, he said.

We hope to talk again with Mayor Ferris – who is back in Juarez – to get his reaction on this latest killing spree.

Also today, we'll talk about ethnic tension in Urumqi in Western China, where clashes between the majority Han and the minority Uyghurs has taken on a new dimension. Thousands of Hans marched in the streets demanding an end to bizarre "syringe" attacks. John Vause has that story.

Drew Griffin will join us again today for part 2 of his investigation on the sale and trade of human body organs. Today, we'll show you how the black market trade can have tragic and deadly results for donor desperate for cash.

Don't forget to take part in today's IDesk poll on whether you think there should be a regulated, above-board market to trade human organs.

It's a very busy day at the IDesk, with several other important developing stories, so it's back to work for me.
