JERUSALEM - Israel has retroactively legalised some 800 homes in four settlements in the occupied West Bank, the interior ministry said.
They included 377 homes in the Yakir settlement, 187 in Itmar and 94 in Shilo in the northern West Bank, as well as 97 more in Sansana in the south of the occupied Palestinian territory, it said.
The decision was taken two weeks ago, but was only reported in the Israeli press on Friday.
It came at a time of heightened tensions between Israelis and Palestinians in the occupied territories, Jerusalem and Israel.
Since the beginning of the month, a wave of attacks against Jews as well as ongoing clashes between security forces and Palestinian protesters have left at least 63 Palestinians, including alleged attackers, and nine Israelis dead.
The international community regards all Jewish settlements in the West Bank as illegal, but the Israeli government makes a distinction between those it has authorised and those it has not.
The wildcat outposts, often little more than a few caravans, are notorious for housing young Jewish hardliners, referred to in Israel as hilltop youth.
Settlements and outposts are seen as major stumbling blocks to peace efforts as they are built on land that Palestinians see as part of a future state, and fuel frustration among Palestinian youth.
Israeli Prime Minister Benjamin Netanyahu has faced major criticism internationally for refusing to halt settlement expansion.
"These aren't new constructions but rather homes built in settlements recognised by Israel in areas that until now didn't have any urban planning," said Hagit Ofran, a spokeswoman for Israeli settlement watchdog Peace Now.
"Even if it doesn't have the same impact that the announcement of new settlements would, it's undeniably a gesture from Netanyahu," she said.
The recent violence in the West Bank, including the killing of a Jewish settler couple in front of their children near the Itmar settlement on October 1, has given ammunition to the Israeli pro-settlement lobby, commentators say.
Israel last announced new settlements in July when the government authorised 300 new settler homes to be built in Bet El in the central West Bank.
Israel occupied the West Bank in the 1967 Six-Day War in a move never recognised by the international community.
Hardline Jewish nationalists see the entire West Bank as part of Israel, which refers to the territory as Judea and Samaria, the names for the ancient biblical kingdoms located there.
