HONG KONG (AP) — For months, China has tried to turn the tables on the U.S. to counter accusations that it hacks America’s computers and networks. Now, former intelligence contractor Edward Snowden may have handed Beijing a weapon in its cyber war of words with Washington.

In an interview with the South China Morning Post newspaper, Snowden claims the U.S. has long been attacking a Hong Kong university that routes all Internet traffic in and out of the semiautonomous Chinese region.
