BLITZER: An Iranian nuclear weapon could be closer to reality than feared. That's just one of the findings in a disturbing new report by the International Atomic Energy Agency. CNN's senior international correspondent, Matthew Chance, has more.</s>MATTHEW CHANCE, CNN SENIOR INTERNATIONAL CORRESPONDENT: Wolf, it's another highly critical report of Iran's nuclear program from the U.N.'S nuclear watchdog. It's filled, of course, with stuff about how Iran continues to fail to cooperate with U.N. inspectors and refuses to answer questions about the alleged military dimensions of its nuclear activities. Iran, of course, says its nuclear program is for purely peaceful purposes. But of most concern say western diplomats is the fact that Iran has stepped up its capacity to enrich uranium adding more centrifuges to its highly secure underground bunker at a place called Fordow which is built into a mountain to defend it against potential air strikes. The report says Iran has effectively doubled its enrichment capacity at Fordow theoretically making it able to make enough material for a bomb much more quickly than it could do previously. So, to report not exactly a game changer, perhaps, but still a very worrying document for those countries who like the United States, Iran's nuclear program very suspiciously indeed -- Wolf.</s>BLITZER: Matthew, thank you. If Israel invades Gaza, it won't be easy for Israeli troops to avoid hitting innocent civilians. It's all a matter of geography. We're going to show you why.
