Hizbullah rockets can not be fired from houses!

While browsing the Egyptian Chronicle I came accross this interesting fact:

The type of missiles being fired by Hizbullah at Israeli cities cannot be fired from within houses, mosques, hospitals or even UN facilities as has been suggested by the IDF. Due to the massive "back-blast" caused by the rocket launchers of these missiles, they can only be fired from open ground.

From a technical standpoint this is utterly true, they types of missiles being fired would have a huge back-blast which makes it impossible for them to be fired from within buildings. They must be set up and used on open ground. So why are Israel targeting houses?

The only conclusions I can draw to, is exceedingly high levels of military incompetence or they are simply targeting civilians – in which case this can no longer be titled as a war against terror, but must be named as an act of war against Lebanon!
Why else would one country attack another’s civilian locations such as inner cities, hospitals, power stations and farms! Back during the Second World War was it not Hitler the enemy of the Jews who did exactly the same?

Anyone who supports Israel need to re-think what they believe in. I believe in a free world, where people can live in peace. What Israel are doing is the complete opposite, and I would like to call for the worlds governments to exert economic and military pressure on Israel, because if you don’t I can foresee so called "terrorist" organizations doing so.
