These pictures of the security barrier were taken from highway 6 (ie. the Israeli side) near Netanya and Kfar Saba. This is an area where a couple of kilometers separate large West Bank villages from the Israeli suburbs and towns north of Tel Aviv. The suicide bombers that entered Netanya generally came from Tulkarm, and in June 2003 a 7-yr. old travelling in a car on highway 6 was gunned down near Qalqilya.
The one above is from the Qalqilya/Kfar Saba area. From the highway there are a few observation towers visible and this is one of them.
The picture above is from around Netanya/Tulkarm.
This one is actually from fairly close up. Near Tulkarm the Israeli side of the barrier extends a couple of meters above a grassy hill next to the highway.
