Five European countries that sit on the UN Security Council on Tuesday rejected Trump's decision to recognise the Golan as Israeli territory and voiced concern the move could have broad consequences.
Qatar's Foreign Ministry rejected the American move and said that the Golan Heights are occupied Arab land.

On Friday, Syria wrote a separate letter urging the council to uphold resolutions demanding that Israel withdraw from the Golan. Rouhani said developments in the Golan Heights were "very risky for regional security".
"The UN's policy on the Golan is reflected in the relevant resolutions of the Security Council, and that policy, again, has not changed", said Stephane Dujarric, spokesman for the secretary general.
Hassan Nasrallah, the leader of Lebanon's Iran-backed Hezbollah movement, and a key Damascus ally, said the move was evidence of United States "disdain and disregard" for the Arab and Muslim world and of global law.
The Golan Heights were seized by Israel from Syria during the Six-Day War in 1967.
Lebanon said the move undermines any efforts to reach peace in the region.
Any attempts by Israel to expand its territory by way of "force and aggression" would only isolate the Jewish state, said the statement. "Canada's long-standing position remains unchanged". European Union countries, including Germany and France, criticized Pres. Trump's decision on Jerusalem. "Any declaration of a unilateral border change goes against the foundation of the rules-based global order".
