MOSCOW, May 14. /TASS/. Iranian Foreign Minister Mohammad Javad Zarif has described as very dangerous the US step on Jerusalem where the US Embassy is due to open on Monday after moving from Tel Aviv.

"We saw a very dangerous behavior of this regime towards Jerusalem," Zarif said at the meeting with his Russian counterpart Sergey Lavrov.

"Unfortunately, opposing international rules and laws has turned into a habit for the US government," he said.

The opening ceremony of the US Embassy in Israel will be held in Jerusalem on Monday. US President Donald Trump announced the decision on moving the diplomatic mission from Tel Aviv on December 6, 2017.

The status of Jerusalem is one of the key issues concerning the Israeli-Palestinian conflict. Israel, which seized the eastern part of the city during the 1967 war, insists that Jerusalem is the single and indivisible capital of the country, while Palestinians wish to make the eastern part of the city the capital of their state.
