Sri Lanka sealed their first win of the tournament with a 25-run victory over Bangladesh.

Both sides lost a wicket to the first ball of the innings but Sashikala Siriwardena's 31 helped Sri Lanka, who had lost their last eight completed games, post 97-7.

Bangladesh - beaten by England on Monday - slipped to 0-2 in reply and were bowled out for 72 off the final ball of the innings.

Nigar Sultana Joty hit two of only three fours in the innings, top-scoring with 20 as Bangladesh remain without a win in the tournament.
