The rallies took place in the Syrian capital, Damascus, as well as other cities in the country’s north, west, south, and east on Tuesday, the official Syrian Arab News Agency (SANA) reported.
Cities where rallies were held included Hasakah, Qamishi, Raqqah, Aleppo, Homs, Hama, Latakia, Dara’a, Quneitra, and Dayr al-Zawr.
A day earlier, US President Donald Trump took a markedly controversial move by proclaiming the Israeli-occupied part of the Golan Heights as Israeli territory.
The highlands have been under Israeli occupation since 1967.
The Arab League, Iran, Russia, Lebanon, Qatar, and Palestinian factions have unanimously denounced Washington’s move. The European Union (EU) has said it will continue to view the territory as occupied.
Syria has pledged to liberate the region.
In late 2017, and in another unilateral move, Trump recognized the occupied city of Jerusalem al-Quds as Israel’s “capital,” also facing global condemnation.
