The United Nation’s High Commissioner for Human Rights said Israel’s plan to annex parts of West Bank will have “disastrous” consequences, AP reported.

"Annexation is illegal. Period. Any annexation. Whether it is 30 per cent of the West Bank, or 5 per cent," Michelle Bachelet said in a Monday's statement.

She urged Israel to reverse its decision and retreat from a 'dangerous path.'

"The precise consequences of annexation cannot be predicted. But they are likely to be disastrous for the Palestinians, for Israel itself, and for the wider region," she added.
