GAZA CITY, Jun 19, 2012 (AFP) - Militants from the armed wing of Gaza's ruling Hamas movement on Tuesday said they had fired 10 Grad rockets at Israel in a rare show of force after Israeli raids killed six.

"This is our answer to the Zionist crimes. It will continue if they carry out more strikes on Gaza," a statement said, with a spokesman confirming it was the first time they had fired such longer-range rockets at Israel since April 2011.
