2011–2014 terrorist attacks in Kenya

From late 2011 to 2014, Kenya experienced an upsurge in violent terrorist attacks. Kenyan government officials asserted that many of the murders and blasts were carried out by al-Shabaab in retaliation for Operation Linda Nchi, a coordinated military mission between the Somalian military and Kenyan military that began in October 2011, when troops from Kenya crossed the border into the conflict zones of southern Somalia.
