Kenyan security forces are claiming control of a Nairobi shopping mall in the midst of a new assault aimed at ending the three-day-old siege, reports the BBC, with large explosions and gunfire heard in the area as smoke billows from the Westgate Mall. "We are in charge of the situation, our people are safe," says the country's interior minister, and the AP reports that he says two militants have been killed thus far in the operation. "We have an idea who these people are and they are clearly a multinational collection from all over the world," says a Kenyan general. The number of hostages inside is believed to be "very, very minimal," says the minister; the military claimed to have freed "most hostages" last night.
