"sing people to protect their weapons."
Sound a little but like a 'gun shanty'.
Israel's practice of deliberately using people as human shields has been raised as an issue on numerous occasions, which is a little different from firing weapons from your home territory - on one occasion, they used a schoolyard to mount an attack on a Palestinian area.
Israel's making legitimate any part of 'enemy territory' is standard practice.

AL-KHALIL (HEBRON): Israeli soldiers invade Palestinian elementary school

March, this year, from 'Christian Peacemaker' eyewitnesses:

"On 4 March, approximately thirty Israeli soldiers entered the Qitoun neighborhood from Checkpoints 29 & 209, provoking stone throwing from schoolboys. At one point, half the forces entered a Palestinian schoolyard and began using stun grenades and tear gas on local children and passersby.   Palestinian teachers prevented the soldiers from actually entering the school building. Soldiers shot canisters in front of the school building and detained three boys under the age of twelve. They later released the boys because they had no pictures of them throwing stones on their cameras.
CPTers have witnessed increasingly aggressive soldier behavior towards schoolchildren during morning school patrols at military checkpoints in the Old City of Hebron. Qitoun neighborhood is home to five schools, including two military checkpoints. On 6 March, CPTers had to carry kindergarteners out of range of the teargas that had incapacitated them.
These military interventions violate the Right to Education (Article 28) from the Convention on the Rights of the Child. CPT records the number of students, teachers, and detentions near these checkpoints as children attempt to make their way to school safely. CPT also documents physical threats, book bag searches, and tear gas use on children."
