In the morning session, Pakistan were bowled all out for 628, with Taijul Islam taking a haul of six wickets during the first innings.

Both Iqbal and his batting partner Kayes secured half-centuries as they reached tea unscathed on 142 runs, but they continued to add to their tally by claiming the highest ever first-wicket stand for Bangladesh.
Iqbal reached a personal milestone by becoming the first batsman for his nation to score seven Test centuries, while Kayes also scored a 100 on the field in Khulna.
The close of play has left Iqbal and Kayes unbeaten on 138 and 132 runs respectively.
