Why? Simple:
Bangladesh has executed the Islamist leader Abdul Kader Mullah, who was convicted of atrocities in the 1971 war of independence with Pakistan....Mullah was a senior leader of the Jamaat-e-Islami party. His trial earlier in the year sparked protests from Jamaat supporters.....Jamaat-e-Islami - which had called the execution politically motivated and warned it would avenge his death - called for a general strike on Sunday.
