The Hague

THE European police agency said on Tuesday it was still too early to determine who was behind a massive cyberattack which has caused global computer chaos, as researchers reported signs of a possible North Korean link.

"We are open to investigate in all directions, but we don't speculate and we cannot confirm this. It's still too early to say anything," said senior spokesman for Europol, Jan Op Gen Oorth. "We are working on it. The investigation is ongoing," he told AFP. "It could come from everywhere, it could come from any country."
