Esther Horgan, a 52-year-old mother of six and a French-Israeli dual national, was found dead Monday in a forest near the Tal Menashe settlement in the north of the Palestinian territory.

Relatives said she had gone out jogging on Sunday and never returned.

A statement from Israel's domestic security agency, the Shin Bet, said: "a suspect in the murder of the late Esther Horgan... has been detained," following a coordinated effort involving the Shin Bet, the army and police.

It described the detained individual as "a Palestinian suspect from the Jenin area," who is being interrogated by Shin Bet agents.

Defence Minister Benny Gantz said Israel had "used every means at the disposal of the Israeli security forces to swiftly find and take into custody a suspect in the shocking murder of Esther Horgan".

Earlier this week, Israel's army had reinforced its presence in the West Bank in response to surging tensions partly linked to Horgan's murder.

Prime Minister Benjamin Netanyahu vowed Monday that Israel will "settle accounts" with Horgan's killer and President Reuven Rivlin visited her family earlier Thursday.

All Jewish settlements in the West Bank are regarded as illegal by much of the international community.

But the settler population has grown in recent years.

There are currently some 450,000 Jewish settlers in the West Bank, living amid an estimated 2.8 million Palestinians.

Tensions between Palestinians and Jewish settlers in the West Bank have repeatedly led to violence.
