The secretary-general of the Palestine Liberation Organisation said US President Donald Trump's decision to recognise Jerusalem as Israel's capital Wednesday destroys any hopes for a two-state solution to the conflict.

"He destroyed the two-state solution," Saeb Erekat, who long served as the Palestinians top negotiator, told journalists after Trump's speech.

Trump "disqualified his country from any role whatsoever" in the peace process, he said.

"As a chief Palestinian negotiator, how can I sit with these people if they dictate on me the future of Jerusalem as Israel’s capital," he added.
