Ahmed Shehzad scored an unbeaten century as Pakistan defeated World Twenty20 hosts Bangladesh by 50 runs to keep alive their hopes of qualifying for the latter stages of the tournament.
Opener Shehzad led from the front for Pakistan, who won the toss and chose to bat in Dhaka.
The 22-year-old finished on 111 not out from just 62 balls as batting partners came and went. Pakistan finished their 20 overs on 190-5, thanks to a late flourish from Shahid Afridi.
Bangladesh have now lost 40 matches in a row against Pakistan. They scored solidly enough in their reply but never really threatened to reach the 191-run win total.
They finished on 140-7, with Shakib Al Hasan top-scoring with 38 runs from 32 balls.
Pakistan's victory means that whoever win their final group game against the West Indies will join India in the semi-finals. Meanwhile, Australia are knocked out of the tournament.
