WASHINGTON — The United States Mission to the United Nations did not join two other permanent members and one non-permanent member of the U.N. Security Council in calling for an emergency meeting on the situation in Egypt on Thursday.

The United Kingdom, France, and Australia all called for a Security Council meeting on the recent violent clashes in Egypt, which is set to take place this afternoon at 5:30 p.m. Deputy Secretary General Jan Eliasson will brief the participants, according to Inner City Press.

A spokesperson for the U.S. Mission to the U.N. did not respond to repeated inquiries about why the United States didn't join its allies in asking for a meeting.

"That's a question for the US Mission to the UN," said U.N. spokesperson Martin Nesirky when asked about the U.S.'s participation.

Meanwhile, U.N. Ambassador Samantha Power is holding a Twitter town hall under the #whatmatters hashtag. Power did not respond to a query from BuzzFeed about the meeting. She has weighed in on the Egypt crisis on her Twitter feed:
