A leading Kenyan university says one person has died and 20 others have been injured following a stampede caused by a drill to test terrorism preparedness.

Strathmore University said in a statement Monday that one staff member had died as a result of injuries received during the drill aimed at testing the preparedness of the university community and emergency response team in the event of an attack.

Some students told local radio station Capital FM that loud bangs and people pretending to be extremist attackers caused panic in at the university causing everyone to flee to the exits. Memories of the April 2 attack by four gunmen from Somali extremist group al-Shabab that killed 147 people are still fresh with many Kenyans, especially university students.
