Rex Tillerson: Trump 'very committed' to Middle East peace

President Donald Trump is "very committed" to the Middle East peace process, US Secretary of State Rex Tillerson said on Wednesday amid global alarm at a US plan to recognise Jerusalem as Israel's capital.

Tillerson said the US believes "there is a very good opportunity for peace to be achieved" between Israel and the Palestinians, despite international outcry over Trump's decision on Jerusalem.

"The president is very committed to the Middle East peace process," Tillerson told reporters at a meeting of NATO foreign ministers in Brussels.

He said a small team led by Trump's son-in-law and senior adviser Jared Kushner has been "engaged in a quiet way" in the region to try to revive peace talks between Israel and the Palestinians.

"We continue to believe there is a very good opportunity for peace to be achieved and the president has a team that is devoted to that entirely," Tillerson said.
