Gaza terrorist Khaled Silawi was sentenced by the Beersheba District Court on Monday to 18 years in prison for firing rockets at Israel.Silawi, 21, was also convicted of spying on Israeli military positions on the Gaza border to plan future attacks.

All wore masks during the training.Later, Silawi was involved in firing rockets at Sderot, including moving the rocket launcher, setting a timer and leaving the area.
