The State Department says U.S. officials are assessing the damage caused by Sunday's natural disasters in Asia.

A spokesman, Noel Clay, says the disasters have caused communication problems, making it hard for U.S. officials to get a full picture of the devastation.

But Mr. Clay tells VOA that Washington will likely offer aid to countries affected by the catastrophe. He says officials may issue a statement later Sunday.

The spokesman says it is "too early to tell" whether the disasters killed or injured any Americans.

U.S. officials are unsure how many U.S. citizens may be in the affected region.
