Non-Metal IEDs with 2 liquids mixing when stepped on - Michael Yon
Michael Yon's Facebook page has this update:

Michael Yon: Am told the enemy has started using IEDs that use no metal. As explained to me by an excellent source, when you step on the bomb, it causes two liquids to mix which then explode.
