Warning that soccer must not be “abused by those who mean evil,” FIFA President Sepp Blatter demanded detailed reasons from the Egyptian federation Thursday, Feb 2 for the stadium riot that killed at least 74 people.

Blatter called for action to prevent a repeat of the post-match violence in a letter to the Egyptian Football Association, whose board was subsequently fired by the prime minister and its members referred for questioning by prosecutors.

The deadliest soccer stadium disaster since 1996 unfolded in the Mediterranean city of Port Said on Wednesday, Feb 1 night following Al-Masry’s league match against Al-Ahly, with fans crushed to death while others were fatally stabbed or suffocated in a stampede, AP reported.
