More 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.

Daniel Luria, the executive director of Ateret Cohanim, said a company registered overseas called Kudram purchased the two buildings with funds from “a group of Jewish investors from Israel and around the world,” while Ateret Cohanim provided guidance and help taking possession of the sites.

“They paid more than appropriate money,” Mr. Luria said.

Mr. Luria noted that the buildings were in an area of Silwan that was once home to a community of Yemenite Jews from the 1880s until the 1930s. For the time being, the two buildings are primarily occupied by guards, yeshiva students and workmen, but Mr. Luria said the plan was for nine families to move in.

In late September, another settler organization, Elad, facilitated the acquisition of 25 apartments in six locations around the City of David archaeological site, which it also runs. It said those homes were purchased by another overseas company, Kendall Finance. Elad said in a statement that it had nothing to do with the acquisition of the latest two buildings. Kendall Finance and Kudram are represented by the same Jerusalem lawyer, Avi Segal.

The Wadi Hilweh Information Center, run by grass-roots Palestinian activists in Silwan, said the two Palestinian families who previously lived in the buildings had vacated them four months ago and appeared to have sold the properties to a Palestinian man who acted as a broker for the settler organization.

The entry of settlers in late September set off an open row between the White House and Prime Minister Benjamin Netanyahu of Israel, who said he was “baffled” by the notion that Jews should be barred from living wherever they wanted in Jerusalem.
