China quadruples rice imports for no apparent reason

BGD, The suicide bombers seem to do a canny job of demolishing concrete buildings in Iraq & Afghanistan when they detonate them. By your definition above, shouldn't they be bomb proof aswell?

The only times suicide bombers have destroyed concrete buildings in Afghanistan or Iraq is with massive car and truck bombs. The buildings themselves did not have anti vehicle measures, so the terrorist vehicles could get inside the buildings or against them.

So, no. The BBC building has anti vehicle measures, so the only suicide bomber likely to get in will have a limited amount of explosives. Suicide bombers with no vehicle always target groups of people, be they in compounds, buildings or where ever, but they do not destroy buildings.

You also need to factor in construction - I doubt very much that a lot of buildings in Afghanistan or Iraq are steel framed with floors / ceilings of concrete beam covered with poured concrete have general public and so suicide bomber access.

Other than government buildings, where people are herded into groups in compounds for the safety of those in the building, the only other buildings that are going to have lots of people in at any one time are mosques and hotels.
