incidents? >> the truck bomb attack was a massive bomb that was driven towards the u.s. military base in eastern afghanistan. destroyed part of the perimeter wall and caused a very high number of injuries. that luckily was a several ton truck bomb that didn't get into the base. this attack was of a very different nature. it's good that you showed the map of how the u.s. embassy compound. a few blocks away, militants were able to go into a building that was under construction bringing with them a large number of grenades. they went up to the roof of the building and then started firing apparently indiscriminately down to the compound and the nato headquarters and i should say several other buildings in the neighborhood. while that attack was going, that took several hours to play
