Egypt detains 4 Al-Jazeera journalists in Cairo

The Qatar-based Al-Jazeera English network says four of its journalists have been arrested by Egyptian authorities after they covered events in Cairo.

Al-Jazeera English says correspondent Wayne Hay, cameraman Adil Bradlow and producers Russ Finn and Baher Mohammed were detained on Tuesday.

The network in a statement Thursday called the arrests "a campaign against Al-Jazeera in particular." The arrests came after the network's Al-Jazeera Mubashir Misr affiliate in Egypt was raided and staff detained.

Egypt's interim government says Al-Jazeera is biased in favor of ousted Islamist President Mohammed Morsi, claims denied by the network.

Al-Jazeera English said authorities are responsible for the journalists' safety and demanded their release. Egyptian authorities today labeled Al-Jazeera Mubashir Misr a "threat to national security" and took steps to ban it.
