UNITED NATIONS (AP) — Israeli Prime Minister Benjamin Netanyahu warned Thursday that Iran will have enough enriched uranium to make a nuclear bomb by next summer and urged the world to draw a clear "red line" to stop it in its tracks.

Saying it was getting "late, very late" to stop Iran, Netanyahu flashed a diagram showing the progress Iran has made toward creating a bomb. He said Iran had already completed the first stage of uranium enrichment, and then he drew his own red line on the diagram to highlight the point of no return — the completion of the second stage and 90 percent enrichment.

"Iran is 70 percent of the way there and ... well into the second stage. By next summer, at current enrichment rates, they will have finished the medium enrichment and move on to the final stage," Netanyahu said. "From there it is only a few more weeks before they have enriched enough for a bomb."
