Telephone companies and the Federal Communications Commission are helping American troops who have run up huge family phone bills calling home from roadside booths in Saudi Arabia.

AT&T said Thursday it is reducing rates by about 30 percent on calls from the desert kingdom to the United States that are made on the company's USADirect service and billed to an AT&T credit card. MCI reduced its rates last week.After receiving several complaints, the FCC said it was trying to get all such rates reduced and to protect military families from having their phone service cut off because they are unable to pay unexpectedly high bills.
