Fox is reporting that the number may be as high as seven and the ROK news folks are saying that the number is as much as 10.
I just checked CNN website:
"North Korea test-launched a Taepodong-2 missile early Wednesday along with several short-range rockets, but the long-range missile apparently failed, U.S. officials said.
U.S. National Security Adviser Stephen Hadley said there were five missile launches in all. One was the Taepodong-2 missile, and the other four were short-range. "
