Hamas' Al Qassam Brigades announces the death of a "martyr":

Al Qassam Brigades, the military wing of Hamas movement, mourned at dawn on Thursday [sic] December 2nd, 2009, one of her members who was martyred while performing a jihadi task in An-Nuseirat camp in the middle of Gaza strip.

The Brigades confirmed in a military communiqué issued on Thursday December 2nd, 2009, the martyrdom of the mujahed Yasser Sabri Radi was during their duty in the middle of Gaza Strip, noting that the mujahed was martyred after a long path of jihad and sacrifice for the sake of their beloved Palestine.

In English, this means that Mr. Radi blew himself up. (There is also a chance that he was accidentally, or purposefully, shot to death by an esteemed terrorist colleague.)

Bring out the candies!

UPDATE: Reports indicate that he was killed in a tunnel collapse.

But he wasn't killed in Rafah, but rather in central Gaza. Which means either he was working on a weapons bunker, on secret tunnels between buildings in Gaza or on a tunnel to attack/kidnap Israelis in Israel.
