Prime Minister Benjamin Netanyahu gave the go-ahead on Sunday to reforms that would end the exemption of ultra-Orthodox Jewish men from compulsory military service, in an about-face hours after 20,000 Israelis marched for change.

Military service is a highly emotive issue for Israelis, most of whom start a two or three-year service at the age of 18. Many are also called up for reserve duty. Ultra-Orthodox Jewish men are exempt to allow them to pursue religious studies.

“Everyone must bear the burden. We will provide positive incentives to those who serve and negative incentives to draft dodgers,” Netanyahu told a meeting of lawmakers from his right-wing Likud party.

At his urging, the Likud legislators ratified the recommendations of a government-appointed panel formulating a new military conscription law that would cancel exemptions for most Jewish seminary students.
