Pro-Palestinian activists demanding an end to the onslaught in Gaza and to American support for Israel plan to surround the White House during a weekend protest, prompting additional security measures, including anti-scale fencing, Reuters reports.

Advocacy and activist groups like CODEPINK and the Council on American Islamic Relations said on Friday that demonstrations were planned on Saturday, marking eight months of Israel’s offensive in Gaza that has killed tens of thousands while causing a humanitarian crisis with widespread hunger and destruction.

“In preparation for the events this weekend in Washington, DC, that have the potential for large crowds to gather, additional public safety measures have been put in place near the White House complex,” a US Secret Service spokesperson said.
