Hamas' Al Qassam website claims that 15 were killed by Israel. And they list one Hamas member who was killed, who was not on the PCHR list:
Ashraf Azzam, 31, killed Friday.
So it is possible that the IDF was even more impressive in its accuracy of killing terrorists - 11 out of 14, or 78%, an almost unbelievable number for urban warfare. (If there was a 15th, I cannot find any mention of it.)
