JERUSALEM - Israeli premier Benjamin Netanyahu told Palestinian president Mahmud Abbas Monday he expected his help in ensuring the return of three kidnapped teenagers, in their first direct political contact since 2012.
The phone conversation took place as Israel pressed a vast search operation in the West Bank to find the three youths, whom Netanyahu has said were kidnapped last week by militants from the Islamist Hamas movement.
As the manhunt entered its fourth day, Israeli troops continued with a massive crackdown on Hamas, arresting scores of its operatives, among them former ministers and MPs.
Since Friday, Israel has arrested more than 150 Palestinians, most of them Hamas members, in the biggest sweep in the territories in years.
As the crisis developed, Netanyahu telephoned Abbas to spell out his demands in what was their first conversation of a political nature in nearly two years.
"I expect you to help in the return of the kidnapped youths and the capture of the kidnappers," Netanyahu told him.
"The Hamas kidnappers went out from territory controlled by the Palestinian Authority and returned to territory controlled by the Palestinian Authority," he said.
So far, there has been no formal claim of responsibility, with Hamas dismissing Israel's accusations as "stupid".
Confirming the phone call between Netanyahu and Abbas, the official WAFA Palestinian news agency said the conversation had "focused on following up on the case of the three (teenagers) who disappeared last Thursday and the ongoing Israeli escalation." Abbas's office issued a statement condemning "the kidnapping of three Israeli youths".
But it also denounced Israel's "raids on Palestinian homes" and the widespread arrest of "many innocents" during which a 19-year-old Palestinian was killed.
The victim, Ahmad Arafat Sabarin, was shot dead during clashes in Jalazoun refugee camp near Ramallah which erupted when troops arrived on an arrest mission, medics told AFP.
An army spokeswoman said soldiers opened fire after "violence erupted and stones were thrown at them from rooftops and alleyways, injuring three." Although arrests have taken place across the West Bank, troops are focusing their search on the southern city of Hebron and the surrounding area, home to some 663,000 Palestinians.
A policy of kidnapping
Overnight, soldiers arrested more than more than 40 Palestinians "including Hamas leadership and operatives" the army said.
Among those picked up was parliamentary speaker Aziz Dweik, a Hamas member who lives in Hebron.
