Looks like I said Thanks too quickly. Unable to view link. Long time waiting and still spinning wheel. I appreciate your time and efforts. Will wait to see if wheel stops in another minute or two, plus try a few other odds and ends.
For other folks who have better eyes for clues, here is a Flickr.com member's photos from yesterday. Looks like he was shooting from a 2nd or 3rd floor window just down the block from the location of the first explosion - flags at barricades location. Link to photos
HERE. Newest images are first. Image number DSC03129 appears to be the last photo before the IED exploded.
I'll keep looking around Flickr for more photo-posters who might have images...
