Syria has condemned as "irresponsible" US President Donald Trump's comments that it was time to recognise Israel's sovereignty over the occupied Golan Heights, BBC reports.
A statement published by the Syrian state news agency said it showed the "blind bias" of the US towards Israel.
It said Syria was determined to recover the area "through all available means".
Israel captured the Golan Heights from Syria in 1967 and annexed it in 1981 in a move not recognised internationally.
Mr Trump's remarks on Thursday overturned decades of US policy on the issue. In a tweet, he said the plateau was of "critical strategic and security importance to the State of Israel and regional stability!"
Israeli Prime Minister Benjamin Netanyahu, who has warned about the "military entrenchment" of his country's arch-enemy Iran in Syria, thanked the US president in a phone call, telling him "you've made history".
