The father of former National Security Agency agent Edward Snowden has arrived in Moscow to meet his son who received asylum in Russia in August.
The 30-year-old systems analyst has been charged in federal court in Virginia with violations of the Espionage Act.
Edward Snowden was stuck at a Moscow airport for more than a month after his arrival in Hong Kong before he was granted asylum in Russia. His whereabouts remain secret.
Mr Snowden's father Lon told Russian television outside the Moscow airport that his son is not planning to return to the United States. He thanked Russia and president Vladimir Putin for sheltering his son, but would not say when or where he would be meeting him.
