ISRAEL has warned Iran to either co-operate with the West over its uranium enrichment program or face military action.

Ron Prosor, Israel's newly appointed ambassador to Britain and one of his country's leading experts on Iran's nuclear program, said that Tehran could enrich enough uranium to make an atomic bomb by 2009.

"At the current rate of progress, Iran will reach the technical threshold for producing fissile material by 2009," he said.

"This is a global threat and it requires a global response.

"It should be made clear that if Iran does not co-operate, then military confrontation is inevitable. It is either co-operation or confrontation."
