Israeli forces destroyed 622 Palestinian homes in the West Bank in 2011, "forcibly displacing" almost 1,100 people, over half of them children, according to a UN Office for the Coordination of Humanitarian Affairs report.
"The current policy and practice of demolitions cause extensive human suffering and should end," said UN humanitarian coordinator for the occupied Palestinian territories, Maxwell Gaylard.
Gaylard said the demolition figures represent a "dramatic" increase on previous years and that tens of thousands of people remain under threat of dispossession, demolition and displacement.
Israel says it only demolishes structures that have been built without required permission. Palestinians say they are rarely granted permits.
Gaylard said he went on Thursday to the village of Anata near Jerusalem where seven Palestinian homes were demolished this week.
The operation was carried out Monday night. The Israeli Committee Against House Demolitions (ICAHD) said Israeli forces demolished Beit Arabiya, a family home and "peace centre" at Anata, that has now been destroyed five times since 1994. Israel's administration for the West Bank said the homes had no permit.
