Batting first Pakistan built a huge total of 201 for 5, with Shahid Afridi adding a brilliant cameo of 49 from 19 balls. Bangladesh mustered only 146 for 6.
Meanwhile, Chris Gayle's unbeaten century sent England to a chastening 6 wicket defeat by West Indies in their opening match of the World T20.
Gayle struck 11 sixes in his 47-ball hundred, the joint-third fastest in T20 internationals and became the first man to score two tons in the World T20.
