"All day today, they've been bombing Georgia from numerous warplanes and specifically targeting (the) civilian population, and we have scores of wounded and dead among (the) civilian population all around the country," President Mikhail Saakashvili told CNN in an exclusive interview.

"This is the worst nightmare one can encounter," he said.

Asked whether Georgia and Russia were now at war, he said, "My country is in self-defense against Russian aggression. Russian troops invaded Georgia."
