The Israeli army sent reinforcements to the area on Wednesday and set up roadblocks near Palestinian villages. "Praying for the bereaved Shevach family", he added.
The file of settlement expansion is the most prominent aspect of the Palestinian-Israeli conflict and one of the main reasons for the end of the last peace negotiations, sponsored by the United States between the two sides in mid 2014.
Nabil Shaath, an adviser to Palestinian President Mahmoud Abbas on foreign affairs, told Xinhua that Israel is using the current USA administration's positions and stances to accelerate its plans for settlement expansion in the Palestinian territories.
U.S. Ambassador to Israel David Friedman.
Israeli forces routinely place entire Palestinian villages under closures following actual or alleged attacks, a policy which rights groups have called "collective punishment".
Israeli security forces are searching for a suspected Palestinian gunman or gunmen who killed an Israeli settler in the occupied West Bank on Tuesday.
Friedman's statement came in response to Tuesday's killing of Raziel Shevah, a 35-year-old Israeli father of six, in a drive-by shooting terror attack near Nablus in northern Samaria, as well as the Palestinians' celebratory reaction to the attack. Shevah lived in the nearby Gilad Farm outpost.More news: House OKs Foreign Surveillance Program; Senate Vote Next
Israeli Defence Minister Avigdor Lieberman meanwhile asked officials to examine the option of retroactively legalising the Havat Gilad outpost, which is home to about 50 families.
The Israeli Peace Now organisation, which is opposed to settlements, said the homes would be constructed in 20 settlements.
Hundreds attended Shevah's funeral at Havat Gilad. His widow said it was his wish to be buried on the hilltop. "We respect his wishes and will bury him in the settlement he loved so much". The IDF is looking into the authenticity of these reports.
The Palestinian Authority also reported in an uptick in stone-throwing incidents by settlers on cars with "Palestinian" license plates.
