Here are some key points about the attack:

• The siege in September 2013 lasted for four days

• Sixty-two civilians, five security officers and the four attackers died

• Initially the authorities said there had been 10 attackers, but then revised the figure down to four. They said all of them had been killed but forensic tests on their remains have never been released

• Rivalry between police and military forces was pointed out as a factor that hindered the response

• Since the attack there has been better coordination and response

• This helped in the response to the Dusit hotel and office complex attack in January 2019 when 21 people died

• In April 2015 four gunmen stormed Garissa University College and killed 148 people, most of them students
