AZA CITY (Ma’an) -- Hamas authorities banned a demonstration planned for the anniversary of the Balfour Declaration in Gaza on Tuesday, a local official said. Mahmoud Zak, an official with the tiny Palestinian Popular Struggle Front said the group had planned to hold a protest outside the United Nations compound in Gaza City. Zak said he informed government officials in advance. But, he said, a Hamas security official called him at midnight Monday to inform him that the demonstration would not be allowed to proceed. "We were surprised by the decision of the internal security to ban the protest where we wanted to deliver a speech on this occasion and hand over a petition to the United Nations in Gaza, something that does not affect them [Hamas]."
