Okay kiddo, let me explain what happened at the United States embassy in Baghdad. The United States has a big office called an embassy in Iraq, which is a country far away. Recently, a group of people who were angry with the United States and their actions in Iraq gathered outside the embassy. They started throwing things and trying to take over the embassy building.
When someone tries to take over another person's property or building by using force, it is called an attack. The United States government had to send more soldiers to protect their embassy and make sure the people trying to attack didn't get inside. They didn't want anyone to get hurt, so they set up security to keep everyone safe.
To make them stop attacking the embassy, the United States sent a message to the leaders of Iraq, which is the country where the embassy is located, and asked them to help. They helped by sending their own troops to the embassy to help guard it and make sure everyone was safe.
In the end, no one got hurt, and the attack was over. The people who were angry with the United States went away, and things went back to normal at the embassy. It's important to remember that even though we may not always agree with each other, we should always try to communicate and find a peaceful solution to problems.
