The oil company BP says it has succeeded in cutting through a ruptured underwater pipe in its latest attempt to stem the huge oil leak in the Gulf of Mexico. Engineers will now lower a containment cap to the seabed and attempt to fit it over what's left of the riser pipe. BP's Chief Executive Tony Hayward said they'd know soon whether the capping would work. Richard Lister reports.

BP's Chief Executive Tony Hayward was upbeat as he announced that they successfully cut away the damaged pipeline, and should soon be able to cap the leaking well. Mr Hayward acknowledged though that what they are doing has never been tried before and there're plenty of challenges still ahead. The cutting tools used by the undersea robots left a jagged edge on the remnants of the pipe which will make fitting of a fully sealed containment device more difficult. Mr Hayward said they hoped to have one in place by the end of the month, but he added they'd have a better idea of the likely success of the capping operation in the next day or so.

More than 80 people have been killed and many more have been injured in a fire that's engulfed several buildings in the Bangladeshi capital Dhaka. Here is Naresh Kaushik.

The fire started with an explosion at an electrical transformer in a building in the Nimtoli area of old Dhaka, and then quickly spread to several nearby residential and industrial blocks. Several shops selling chemicals made the blaze worse.
