In the run-up to the March 2013 elections, tensions ran high among local journalists, who feared a repeat of the violent aftermath of the disputed 2007 vote in which the press was targeted and harassed in connection with news coverage. Several journalists were threatened or attacked throughout 2012 in reprisal for their reporting on official corruption. CPJ found that most of the anti-press episodes took place in Western Kenya. The installation of fiber-optic cable networks drove up the number of Internet users. With its Internet penetration having doubled since 2010, Kenya boasted the highest rate in East Africa. The country also leads East Africa in mobile phone use with 29 million clients, according to International Telecommunication Union data. Kenya continued to be the main regional refuge for journalists fleeing their home countries in fear of attack or imprisonment. Since 2007, at least 52 journalists have resettled in Kenya, but often under extreme hardship.
