The activists from the Scottish Palestine Solidarity Campaign were at Manchester Airport ahead of scheduled flights to Tel Aviv today.
Palestinians have no airport of their own and Israel controls the borders of the occupied West Bank.
Israel’s government is understood to have sent a list of names of suspected activists to several international airlines. Among the carriers is easyJet, who confirmed they would refuse boarding to the UK passengers named by Israeli border authorities.
Some 1,500 campaigners from around the world are trying to reach Palestine over the coming days to raise awareness of how Israel controls access into Palestinian areas.
Chairman of the Scottish Palestine Solidarity Campaign Mick Napier described the situation as “outrageous”, adding: “We anticipated this, and we still hope to get to Israel as planned.”
