RAMALLAH, West Bank — The Palestinian president on Wednesday defended his policy of security cooperation with Israel in a politically risky speech to senior Arab officials, even as Israeli forces escalated their most extensive West Bank crackdown in years in response to the apparent abduction of three Israeli teenagers.
President Mahmoud Abbas’s comments were quickly condemned at home and shined a light on one of his most controversial policies — working with the Israeli military to keep the Hamas militant group, which Israel accuses of carrying out the kidnapping, in check.
The three youths, Eyal Yifrah, 19, Gilad Shaar, 16, and Naftali Fraenkel, a 16-year-old with dual Israeli-American citizenship, disappeared late Thursday while hitchhiking home from Jewish seminaries in the West Bank. Accusing Hamas of being behind the apparent abduction, Israel has launched a widespread crackdown on the group, arresting scores of members while conducting a feverish manhunt for the missing youths.
In a speech to Muslim leaders in Saudi Arabia, Abbas condemned the kidnapping, saying it had caused heavy damage to the Palestinians and that his forces were helping search for the missing teens.
‘‘We are still looking and searching to find out who carried out such an act,’’ Abbas said. ‘‘He who committed such an act wants to destroy us.’’
‘He who committed such an act wants to destroy us.’
Abbas said he hoped to rescue the teens ‘‘because these youths are human beings, and we want to protect human lives.’’ While accusing Israeli Prime Minister Benjamin Netanyahu of exploiting the crisis to inflict pain on the Palestinians, he also said the coordination with Israel is a Palestinian interest as well.
‘‘We don’t want to go back to chaos and destruction, as we did in the second [Palestinian] uprising,’’ he told the Organization of Islamic Cooperation in Jeddah, Saudi Arabia. ‘‘I say it openly and frankly. We will not go back to an uprising that will destroy us.’’
His comments were remarkable because of his audience and because security coordination is widely unpopular among Palestinians. They also put additional strains on the new unity government that Abbas formed earlier this month with backing from Hamas.
The government was meant to end a rift stemming from Hamas’s takeover of the Gaza Strip from Abbas seven years ago. But tensions remain, and Hamas is still in control of Gaza, while Abbas governs from the West Bank.
Abbas’s comments quickly drew condemnation from Hamas. ‘‘These comments are based on the Zionist narrative,’’ said Sami Abu Zuhri, a Hamas spokesman in Gaza.
In Washington, Abbas’s words won praise from the State Department. ‘‘We were encouraged by President Abbas’s strong statement to the Arab and Islamic foreign ministers today in Saudi Arabia,’’ spokeswoman Jen Psaki said.
She said the United States has been in touch with both sides, urging restraint and continued security coordination.
Coordination between the sides was strengthened after Hamas seized Gaza in 2007, leaving Abbas only in control of the autonomous areas of the West Bank.
Abbas subsequently launched a crackdown on Hamas in the West Bank, to prevent a Hamas-led coup there. In the past seven years, forces loyal to Abbas have shut down many Hamas-linked charities and schools and have tried to dry up sources of Hamas funding.
Hamas, an offshoot of the regionwide Muslim Brotherhood, is deeply rooted in Palestinian society. The movement’s political goal is an Islamic state in all of historic Palestine.
