Directions: Read the short story below and answer the question. "Eight Families From California Left Behind"

In 2021 the U. S. decided to end its longest war and withdraw its soldiers from the country. Suddenly, however, the government fell and chaos gripped Kabul. In August, U. S. troops hurried to get Americans and allies out of the country, and the last U. S. soldier left on August 31. Yousef's wife and children were among eight families from El Cajon who were left behind.
Yousef's family and several other families finally got out of Afghanistan. The Cajon Valley Union School District and their representative in Congress, Republican Darrell Issa, assisted them.
Several of the families spoke to reporters last week. Yousef asked that only his first name be used in this story because he still has relatives in Afghanistan who could be at risk.
The parents described running with their kids as gunfire whizzed overhead. One father said he was beaten by the Taliban. They said they were kept from getting to the airport by Taliban checkpoints.
They said they are grateful to be back in the U. S., but that they worry about the family members unable to get out.

Question: Why did Yousef only want to give his first name?
