The last victim was Rina Shnerb, 17, killed by an IED on August 23, 2019.
That attack was done by the PFLP - the same PFLP who is linked to anti-Israel NGO DCI-Palestine in news over the past couple of days. The PFLP is linked to a number of NGOs to use them as another avenue to attack Israel under the guise of human rights.
Needless to say, none of the PFLP-linked NGOs said a word against Rina's murder.
Still, a six month stretch without a terrorist murder in Israel is quite unusual; the last time I can see a stretch that long was seven months between October 29, 2011 (Moshe Ami, 56, rocket hitting Ashkelon) and June 1, 2012 (Staff-Sgt Netanel Moshiashvili, 21, shot on patrol near Gaza).
Let's hope the current streak continues for a long, long time.
