YMCA attacked in Gaza...

Gee, can we blame Israel for this???

Unidentified assailants riding a motorcycle threw a hand grenade into a YMCA building in the Gaza Strip on Tuesday, a local human rights group reported.

The Palestinian Center for Human Rights said in a statement Wednesday that shrapnel from the grenade spread over a playground connected to the central Gaza City facility but no damage or injury was otherwise reported.

Police have opened an investigation into the attack, which the group strongly condemned as the latest example of a "state of security chaos" plaguing the occupied Palestinian territories.

The same building has come under attack before, the rights group said, recalling an incident in February 2008 in which unknown persons detonated explosives in the building's library.
