The Palestinian Authority and the Arab League on Saturday condemned the Czech Republic's opening of a diplomatic office in Jerusalem as a violation of international law.
Prague opened a Jerusalem branch of its Israel embassy, which is located in Tel Aviv, on Thursday.
The inauguration was attended by Czech Prime Minister Andrej Babis, two weeks after Israel sent 5,000 Moderna COVID-19 vaccine doses to the Czech Republic under a "vaccine diplomacy" programme that later came under legal scrutiny and was frozen.
The Palestinian Foreign Ministry called Prague's move "a blatant attack on the Palestinian people and their rights, a flagrant violation of international law," and said it would harm peace prospects.
