The Islamic Jihad-linked Palestine Today website reports that "informed sources said that the Israeli soldier captive in Gaza, Gilad Shalit, was wounded in a raid by Israeli planes."
Further reading shows that these "informed sources" was some website called Islam Today (not sure which of those it was), and there is no confirmation by anyone who would know the truth.
It is pretty obvious that this is just a disinformation campaign to try to get Israel to stop attacking terrorist targets, but it is one that at least some Palestinian Arab journalists are eager to be a part of.
UPDATE: It looks like the IDF predicted such a scheme.
