TEHRAN, May 14 (Xinhua) -- Iran's Foreign Ministry on Monday urged Muslims to unite against U.S. relocation of embassy in Israel, according to the state TV.

In a statement, the foreign ministry warned of the consequences of the relocation of the U.S. embassy from Tel Aviv to Jerusalem.

The move by the United States will only further strengthen the resolution and determination of the oppressed Palestinians in confronting and resisting occupation, it said.

Besides, "it will intensify anti-Zionist and anti-U.S. moves in the region and across the world," it said.

The statement also called on Islamic nations and governments "to remain vigilant in the face of plots hatched by the Zionist regime (of Israel) and its allies."

The new U.S. embassy in Jerusalem was opened on Monday. Israeli and U.S. officials gathered in the city amidst deadly clashes in the Gaza Strip.
