Al Jazeera says that its reporters and presenters have been receiving threats from government loyalists in the Arab world, because of their coverage of Arab uprisings and protests.
They have been receiving threatening emails and female on-air staff have been receiving obscene threats.
The network has been beefing up its security procedures and is hiring investigators to track down the sources of threats that are posted on Facebook and elsewhere.
Almost all al Jazeera reporters have canceled their summer vacations to Arab countries outside of Doha for fear for their families' safety.
Al Quds al Arabi also has received email threats and one bomb threat in reaction to its coverage of the riots, forcing them to evacuate.
