The director of the Central Intelligence Agency is again warning about Russia's computer hacking abilities, saying the country has "exceptionally capable and sophisticated cyber-capabilities."
CIA Director John Brennan spoke in a U.S. television interview on September 11, in which he was asked about recent computer intrusions at the Democratic National Committee.
He didn't specifically blame Moscow for the break-ins, although other intelligence and congressional officials have.
But he did cite what he said was Moscow's aggressive intelligence collection.
"I think that we have to be very, very wary of what the Russians might be trying to do in terms of collecting information in a cyber-realm, as well as what they might want to do with it," he told the CBS program Face The Nation.
The issue of Russian hacking has become prominent in the U.S. presidential race, with embarrassing e-mails from Democratic Party officials being leaked just before the convention that endorsed Hillary Clinton's candidacy for the White House.
Her opponent, Donald Trump, has downplayed the danger of Russian meddling in the U.S. election, saying in an interview broadcast on Russian government-funded TV that he thought it was unlikely the Kremlin was trying to do so.
