PS: I'm having some problems

"We reached school, the first thing I saw was a classmate crying, I hurried asking what happened and she told me "I saw him dying there! We couldn't do anything" I just didn't know what to ask more and hurried to the class, about 3 other girls were crying and the number was increasing, appearantly, a girl saw a man putting a bomb at the side of the road and before being able to do anything, a stryker passed, nothing happened, a bus full of secondary school students passed and the bomb exploded, the American soldiers got frightened and started shooting randomly everywhere.. The students in the bus lied on the ground, one of them shouted for the others to say al-shahada, he got a bullet and died, a teacher got a bullet too but she didn't die.."
