JERUSALEM — Jewish settlers moved under armed guard into two buildings in the predominantly Palestinian East Jerusalem neighborhood of Silwan early Monday, weeks after the Obama administration denounced an earlier influx of settlers to the area as “provocative.”

The latest acquisitions were facilitated by Ateret Cohanim, a nongovernmental organization that establishes educational institutions and settles Jews in predominantly Arab areas in and around the Old City of Jerusalem. Its goal is to prevent any future political division of the territory, which Israel conquered from Jordan in 1967 then annexed in a move that was never internationally recognized.

Adnan Husseini, the Palestinian Authority governor of the Jerusalem district, described the overnight entry of settlers as “shocking,” and said the deal to purchase the properties was being investigated.

Silwan, where several hundred Jews now live among about 50,000 Palestinians, has been a target for Jewish settler organizations since the late 1980s. Located on the slopes just south of the Old City walls, it sits in the shadow of the Al Aksa Mosque, revered by Muslims, and is also the site of the ruins of what is believed to be the City of David, an ancient Jewish landmark. Most of the world considers the area illegally occupied by Israel, and the Palestinians covet it as part of the capital of a future state.
