Twitter might be a U.S. company, but Twitter users are polyglots.

That’s the message the U.S. Embassy in Cairo sent the Muslim Brotherhood on Thursday when the diplomats called out the Egyptian political group for tweeting English messages supporting the United States on its official English account, @ikhwanweb, while rooting for protesters in Cairo on its Arabic feed.

“Egyptians revolt for the Prophet’s victory in front of U.S. embassy,” the Brotherhood’s Arabic account said, according to Businessweek.

U.S. Embassy employees tweeted the discrepancy.

Muslim Brotherhood leaders have called for a nationwide protest in Cairo tomorrow over an anti-Islamic video that was posted on YouTube and has led to demonstrations and attacks on U.S. embassies across the Middle East.

The Brotherhood responded that it only endorses “peaceful” protests.

.@dlachine We condemned both movie as well as violent protesting in all our statements Arabic & English, but ppl ve rt to peacefully protest

President Obama said in interviews Wednesday that Egypt is neither an enemy nor an ally of the U.S.
