PAT Robertson, an American Conservative Christian broadcaster says God told him a terrorist attack will result in "mass killing" in the United States in the second half of 2007.
"I'm not saying necessarily nuclear, the Lord didn't say nuclear," Mr Robertson said on his television show The 700 Club. "It'll be mass killing, possibly millions of people, major cities.
"The evil people will come after this country and there's a possibility, not a possibility, a definite certainty, that chaos is going to rule."
Mr Robertson told viewers they should not be afraid because "if you get blown up or something, you go to heaven; that's the worst thing that will happen to you".
He said God conveyed this message to him during an annual prayer retreat. He said he has received other messages during past retreats.
The broadcaster's 2006 forecast of heavy storm damage in coastal areas was followed by the second-lightest hurricane season since 1995. However, he said his prediction was borne out by storms in New England, Denver, the Pacific Northwest and the Philippines.
God did not warn him of any natural disasters this year, he said.
Mr Robertson, 76, reaches about a million viewers daily on the Christian Broadcasting Network, which he founded. He is credited for helping to shape political views of evangelical Christians, a vibrant force in the Republican Party, and campaigned for the presidency as a Republican in 1988.
He claims on his website that he can leg-press 2,000lb, thanks to an energy drink he promotes.
