It is a habit with them.
Longtime blogger Meryl Yourish used to do a "Open the Gates of Hell" watch so I decided to do a quick search of when else Hamas and other terror groups made that same promise.
November, 2001 - in response to Israel's killing of Mahmoud Abu Hanoud
January 2002 - Fatah warning Israel not to hurt a terrorist in custody
September 2003 - after an unsuccessful attempt to kill Sheikh Yassin
March, 2004 - after the successful attempt to kill Sheikh Yassin
July 2005 - after Israel killed 7 Hamas terrorists
November 2005 - After Israel killed a member of Fatah and Hamas
February 2006 - when Israel withheld money transfers to Gaza
June 2006 - by the PRC after their founder was killed
April 2007 - a general warning against an Israeli invasion of Gaza
May 2007 - after Israel fired at the house of Ismail Haniyeh
August 2008 - Islamic Jihad general warning against Israel
December, 2008 - Hamas threatened this before Cast Lead
March 2011 - threat against UNRWA if it started teaching about the Holocaust in Gaza schools
It looks like every time the terrorists "open the gates of hell," they fall right in.
