The United States government, which has difficulty controlling its own borders, has agreed to help Saudi Arabia secure its dangerous border areas near Yemen.
"It is a very rough border, very difficult to protect from illegal crossings," U.S. Homeland Security Secretary Janet Napolitano said.
"So many of our discussions were about how to protect a very tough, geological, topographical border from illegal crossings," Ms. Napolitano said during a visit to the Saudi kingdom on May 31.
