"Armed police investigating the 21 July attempted bombings have made a number of arrests and surrounded flats in west London in "significant" operations. The area, around Dalgarno Gardens, North Kensington, has been cordoned off, and the area has been evacuated.
Eyewitnesses say they heard three shots and a large explosion as officers wearing gas masks entered a property.
Police are seeking three men in connection with the attempted bomb attacks in London. Muktar Said Ibrahim, 27, also known as Muktar Muhammad Said, has been named as one of the three.
Police are continually shouting at someone in the flat to come out. They are addressing him as "Muhammad". The police are asking him: "What is the problem? Why can't you come out? "Take your clothes off. Exit the building. Do you understand?"...
Scotland Yard say they are not aware of firearms having been used. "
