An attacker opened fire early on Tuesday at the entrance to a town outside Jerusalem, killing three Israelis and critically wounding a fourth, Israeli police and medical services said.
Aside from new construction, Mladenov said the demolition of Palestinian homes and schools continued, but at a significantly lower rate.
"As a result of the attack, three Israelis were killed, another one wounded", the statement said.
The shooter was identified by police as a 37-year-old man from Beit Surik, a Palestinian village near Har Adar, who carried a work permit for the settlement.
A police spokesperson said they were investigating if the terrorist was a worker or if he had only hidden among them.
Har Adar is an upscale settlement west of Jerusalem, on the border between the West Bank and Israel.
The wounded Israeli is in a serious condition and is being treated at the Hadassah hospital in Jerusalem.
The violence had greatly subsided in recent months. However, he "aroused the suspicion" of officers on the scene and then took out a gun and shot at the Israelis.
"There's no point negotiating with someone who just fans the flames of terror and continues to pay terrorist's families", she said. Israel says a lot of them were attackers and others died in clashes with Israeli forces.
Since September 2015, Palestinians have killed 48 Israelis, two visiting Americans and a British tourist in stabbings, shooting and car-ramming attacks.
