On September 28 and 29, security forces raided the homes of the six journalists - Mohamed Ashraf Abu Emeira, Abdallah Qadry, Islam Barakat, Omar Helal, Mohamed Mahmoud and Mohamed Adel - who constitute the entire team working for Matsada2sh (Arabic for "Don't believe"). The arrests bring the number of journalists detained in Egypt to 24.

"It is a first in Egypt: an entire newsroom behind bars," press freedom watchdog Reporters Without Borders (RSF) said, criticising the authorities for failing to reveal the journalists' whereabouts.

"It's a violation of the Egyptian Constitution, even though this is common practice. Journalists detained in Egypt are often forcibly disappeared for several days before being officially charged and brought before a court," the group added.

According to multiple accounts by rights groups, the officers confiscated the phones and laptops belonging to the journalists as well as those of their family members during the raids. They also did not present any arrest warrants and refused to disclose where the journalists would be held.

The interior ministry later published a statement confirming the arrests and accusing the journalists of running an unlicensed platform that is "run from abroad" and of spreading "fake news".

It also accused its journalists of being affiliated with the Muslim Brotherhood, the country's largest opposition group that has been outlawed under the government of President Abdel Fattah el-Sisi since 2014.

One of the platform's editors was previously detained in 2023 over similar allegations but was released two days later.

Matsada2sh was founded in 2018 as a fact-checking outlet that corrects misleading or inaccurate information by various sources, including those by official government sources or opposition media.

"Independent journalism is critical in any free society and Egyptian authorities' failure to allow free exercises of expression to thrive flies in the face of a purported commitment to dialogue, transparency, anti-corruption, and regional leadership," more than 80 rights groups and independent media outlets said in a statement.

"The crackdown on the Matsada2sh platform and these arrests are alarming escalations on independent media and freedom of expression that cannot be allowed to stand."

One of the founders of Matsada2sh, Abdelrahman Mansour, who is not based in Egypt, told the Associated Press on Thursday that the families do not know where the journalists are.
