Spokesperson of the high commissioner Rupert Colvile says: "Given his severe disability which must have been clearly visible to those who shot him, his killing is incomprehensible and it's a truly shocking act".

The UN General Assembly will hold a special session on Thursday, following a request by Arab and Muslim states. She said the veto - the first cast by the U.S.in more than six years - was done "in defense of American sovereignty and in defense of America's role in the Middle East peace process".
Mr Trump's Dec 6 decision to recognise Jerusalem broke with worldwide consensus, triggering protests across the Muslim world and drawing strong condemnation.
"What we witnessed here in the Security Council is an insult", she said.
President Trump affirmed that declaration by officially recognizing Jerusalem as the capital of Israel. Palestinians want the capital of an independent Palestinian state to be in the city's eastern sector, which Israel captured in a 1967 war and annexed in a move never recognised internationally.
