An Israeli teen was killed and her father and older brother were seriously wounded on Friday morning when an explosive device was triggered as the family was visiting the Danny Spring near the settlement of Dolev in the Binyamin Regional Council in Samaria.
Lod resident Rina Shnerb, 17, sustained mortal wounds in the terrorist attack and died at the scene. Her father, Eitan, and brother, Dvir, both suffered serious wounds.
Prime Minister Benjamin Netanyahu, who is also the defense minister, was scheduled to meet with security officials on Friday afternoon.

"I offer Rina Shnerb's family my deepest condolences and wish the wounded a speedy recovery. We will continue to bolster the settlement enterprise and we will strike our enemy down. Security forces are sparing no effort to find these heinous terrorists. We will find them. Israel's reach is long and we will settle the score with all who wish to harm us," Netanyahu said in a statement.
Hamas lauded the attack, saying it was a response to Israel's "aggression."
Hamas leader Ismail Haniyeh issued a statement saying the attack was "proof of the vitality and courage of the Palestinian people, who will not surrender to the crimes of the occupation."
He called the attack "a heroic act."
According to initial reports, the attack occurred at the Danny Spring near Ein Buvin. Officials at the scene said that the explosives were apparently planted on the path leading up to the spring and were triggered as they were walking down the path.
Magen David Adom emergency services personnel were scrambled to the scene to provide first aid. Because the spot is difficult to access, MDA paramedics moved the father, 46, and his 19-year-old son to a spot where military helicopters were waiting. They were then airlifted to Hadassah Ein Kerem Medical Center in Jerusalem.
Magen David Adom reported on Twitter that the son had sustained multiple injuries to his abdomen and extremities. He was unconscious and on a respirator, MDA said. The father's condition was later upgraded to moderate.

Security forces and emergency medical personnel were at the scene of the suspected IED bombing near Dolev on Friday after initial reports of the explosion were received, and a large contingent of security forces fanned out in the area following reports of a car that was seen driving away from the scene of the blast.
Security forces were sweeping the area for suspects, with a focus on the area around Ramallah.
Residents of Dolev were under orders from security officials to remain indoors and report any suspicious activity.
In an interview to Channel 12 News, Habayit Hayehudi MK Moti Yogev, a resident of Dolev, described the spring as "full of life" and flowing water all year round, even in the summer.
Yogev said that hundreds of Israelis visit the spring, as well as the many other springs throughout Judea and Samaria, on Fridays and holidays. Israelis who visit the area are usually instructed to arm themselves and inform security forces of their destination.
"But the Arabs show up and bring death to a place full of life. No Jew has ever attacked an Arab there," Yogev said.
Israel must strengthen its deterrence by strengthening settlements, Yogev said.
Yisrael Gantz, head of the Binyamin Regional Council, spoke to Israeli media at the scene of the attack and called on Israel to apply sovereignty in Judea and Samaria.
