A top Palestinian official has called for Muslim countries to boycott products from the United States and Israel in the wake of the Organization of Islamic Cooperation (OIC) summit held in Istanbul on Wednesday.

Mahmoud Sidqi al-Habbash, a senior adviser to Palestinian President Mahmoud Abbas, spoke to Anadolu Agency after the OIC extraordinary summit, which saw the bloc recognize East Jerusalem as the capital of Palestine.

 I believe it is a duty for Muslims to boycott Israeli products,” Habbash said. “Until Israel accepts and acts accordingly with international law, we call [on Muslims] to boycott Israeli products,” he said.

In regards to the extraordinary summit, Habbash said it displayed Muslim countries’ “seriousness” against the U.S. decision to recognize Jerusalem as the Israeli capital and to move its embassy to the holy city.

 We are serious. We will not tolerate when it comes to issues regarding to our holy sites,” he said, warning: “We can take some painful steps against their [U.S. and Israel] interests in the region and the world.”

In response to a question if U.S. products would be included in the boycott call, the top adviser said:

 “Right now, after the U.S. move, yes, it also regards boycotting U.S. products. America and Israel are on the same side. It is against the interests of the Muslim Ummah."
