CHITTAGONG: India's seamers ripped through Bangladesh's middle-order to leave the hosts on the back foot in the fog-hit first cricket Test here on Tuesday.

Bangladesh, replying to India's modest 243, slumped from their overnight score of 59-3 to 118-6 in the shortened morning session of the third day's play.

Mushfiqur Rahim was unbeaten on eight and Mohammad Mahmudullah was on 14, with Bangladesh trailing by 125 runs with four wickets in hand.

Play was delayed for the third successive day due to dense fog over this coastal city which permitted 63 of the stipulated 90 overs on the first day and just 24.5 overs on the second day.

Bangladesh added nine runs to their overnight score when seamer Ishant Sharma had former captain Mohammad Ashraful caught in the slips by Rahul Dravid for two.

Bangladesh skipper Shakib Al Hasan cracked four boundaries in his 17, but his aggressive intentions did not last long.

The left-hander attempted to glide Zaheer Khan over point but India's stand-in captain Virender Sehwag jumped in the air at gully to pick up a sharp chance.

Raqibul Hasan (17) was the third batsman to fall in the morning session, edging a lifting delivery from Shanthakumaran Sreesanth to wicket-keeper Dinesh Karthik.

The second and final Test of the short series will start in Dhaka on January 24.
