The US will label the Boycott, Divestment and Sanctions campaign, which seeks to isolate Israel over its treatment of the Palestinians, as anti-Semitic, Secretary of State Mike Pompeo said Thursday, calling the movement "a cancer".

Washington "will regard the global anti-Israel BDS campaign as anti-Semitic... We want to stand with all other nations that recognise the BDS movement for the cancer that it is," Pompeo said in a joint appearance with Israeli Prime Minister Benjamin Nentayhu.

Pompeo also said he will visit the Golan Heights in a controversial visit by a top US diplomat to the Syrian territory occupied by Israel since 1967.

"Today I will get a chance to visit the Golan Heights," Pompeo said.
