The Organization of Islamic Cooperation (OIC) slammed the opening of an office to the Czech Embassy, and another to the Kosovo Embassy in Jerusalem.

"This act violates international law and all relevant UN resolutions, particularly UN Security Council resolution 478, which prohibits the establishment of diplomatic missions in the occupied city," said OIC in a press statement.

OIC called for abstaining from causing prejudice to the historical, legal and political status of the occupied city of Jerusalem, which forms an integral part of the Palestinian territory occupied since 1967.
