Israel was not invited because it was not part of the contact group, Albares said, adding though that "we will be delighted to see Israel at any table where peace and the two-state solution are discussed".
Spain, Ireland and Norway are among Western countries to officially recognise a Palestinian state, prompting Israel to pull its ambassadors from Madrid, Dublin and Oslo last month.
"This compounds the suffering of Palestinians in the Gaza Strip and the West Bank and further endangers their safety and wellbeing,” said ILO Regional Director for Arab States Ruba Jaradat.
The call came less than a week after Spain, Ireland and Norway officially recognised a Palestinian state.
