Okay kiddo, have you heard of a group of people called the United Nations? They are a group of many countries that work together to make the world a better and safer place. One of the things they do is help solve problems in different countries.
A long time ago, in a country called Lebanon, some bad things were happening. These things made people scared and unsafe. So, the United Nations decided to send a group of people called the United Nations Interim Force in Lebanon (UNIFIL) to help.
UNIFIL is made up of soldiers from different countries who work together to make sure that the people in Lebanon are safe. They do things like patrol areas to make sure nobody is doing anything dangerous, check people's identification to make sure they are not up to anything bad, and help people who need it.
UNIFIL has been in Lebanon for many years now, and they are working hard to make things better for the people there. Like when you help someone who needs it, UNIFIL is helping the people of Lebanon and making sure they can live their lives without fear.
