Aren't the blocks made of concrete? A 5.56 round isn't likely going to penetrate any building material besides glass.
I obviously meant soldiers who were competent and didn't indiscriminately fire their 5.56mm weapons which cannot penetrate concrete while fighting a handful of militants.
And the source for that information is given above.
A 5.56mm round still isn't going to penetrate it. But even if they do use more powerful weapons, the secret to not killing thousands of innocent civlians when fighting a handful of militants who are actually armed is to simply be careful and responsible, instead of deliberately doing just the opposite.

Oh, and btw, your source for that huge number was some iranian news thingy? Do you have something from the BBC or a more legitimate source that says that?Single 5.56mm rounds are not effective against structural materials (as opposed to partitions) when fired at close range - the closer the range, the less the penetration. The 5.56mm round is affected more by close ranges than the 7.62mm or .50 rounds.
■5.56 mm Maximum Penetration. For the 5.56mm round, maximum penetration occurs at 200 meters. At ranges less then 25 meters, penetration is greatly reduced. At 10 meters, penetration by the 5.56mm round is poor due to the tremendous stress placed on this high-speed round, which causes it to yaw upon striking a target. Stress causes the projectile to break up, and the resulting fragments are often too small to penetrate.
■Reduced Penetration. Even with reduced penetration at short ranges, interior walls made of thin wood paneling, sheetrock, or plaster are no protection against 5.56mm ball ammunition rounds. Common office furniture, such as desks and chairs, cannot stop these rounds, but a layer of books 18 to 24 inches (457 to 610 mm) thick can.
■Wood and Cinder Blocks. Wooden frame buildings and single cinder block walls offer little protection from 5.56mm rounds. When clearing such structures, soldiers must ensure friendly casualties do not result from rounds passing through walls, floors, or ceilings.
■Armor-Piercing Rounds. Armor-piercing rounds are slightly more effective than ball ammunition in penetrating urban targets at all ranges. They are more likely to ricochet than ball ammunition when the target presents a high degree of obliquity.
The following common barriers in urban areas stop a 5.56mm round fired at less than 50 meters:
■One thickness of well-packed sandbags.
■A 2 inch (51 mm) non-reinforced concrete wall.
■A 55 gallon drum filled with water or sand.
■A small ammunition can filled with sand.
■A cinder block filled with sand (block will probably shatter).
■A plate glass windowpane at a 45° angle (glass fragments may be thrown behind the glass).
■A brick veneer.
■A car body (round will penetrate but normally not exit).
Although most structural materials repel single 5.56mm rounds, continued and concentrated firing can breach some typical urban structures.
■Breaching Masonry Walls. The best method for breaching a masonry wall is by firing short bursts (three to five rounds) in a U-shaped pattern. The distance from the gunner to the wall should be minimized for best results ranges as close as 25 meters are relatively safe from ricochet. Ballistic eye protection, protective vest, and helmet should be worn.
■Ball and Armor-Piercing Ammunition. Ball ammunition and armor-piercing rounds produce almost the same results, but armor-piercing rounds are more likely to fly back at the shooter. The 5.56mm round can be used to create either a loophole about 7 inches (178 mm) in diameter or a breach hole large enough for a man to enter. When used against reinforced concrete, 5.56mm rounds cannot cut the reinforcing bars.

*Penetration only, no loophole.
Not sure about drywall, but masonry will certainly stop them.Here in Mexico the walls are standard brick and mortar with plaster coating and and from what I've seen 5.56 rounds will knock out big chunks but won't penetrate. I've heard they even have trouble penetrating layers of drywall. They really like to fragment rather than penetrate.
As far as stopping a .223 round, a cinder block looks like a pretty good thing to have.
This gets back to what I was saying about being competent and responsible. You have to go out of your way to kill civilians inside most houses when fighting a handful of criminals in the streets. Besides, I doubt there was a single innocent Palestinian civilian who was actually killed in this manner.Although most structural materials repel single 5.56mm rounds, continued and concentrated firing can breach some typical urban structures.

Besides, I doubt there was a single innocent Palestinian civilian who was actually killed in this manner.
According to the sources, Israeli troops chased an Islamic Jihad operative into a house, then came under grenade and small-arms fire from the residence.
A Palestinian fled the house and was killed, the sources said.
IDF troops entered the house during the firefight and found two Palestinians dead inside.
