Work accident!

Two Hamas members offed themselves in northern Gaza. Hamas blames Israel, but it is not quite sure how to blame Israel:

Hamas initially said the men were killed in an Israeli airstrike, then said they had been shot and later said they were killed by Israeli tank fire.

But the Israeli military says it wasn't involved.

YNet fills in the blanks:

Two Hamas gunmen were killed in what appears to be a malfunction of an explosive device they were attempting to place near an area of Gaza's border fence regularly patrolled by soldiers, Palestinian sources reported Tuesday.

Preliminary reports said the two were killed an Air Force strike, but the reports turned out to be false.

The 2009 PalArab self-death count rises to 178.
