In 2009, there was a big explosion that happened in a place called Diyala Province. It was a very tragic event that caused a lot of people to get hurt and some even passed away. Some people had set off a bomb in a busy market area where lots of people were shopping and going about their day. It was a very terrible thing to happen and made a lot of people very sad. The people who did this were very bad and it's important to remember that we should always try to be kind and not hurt others.
