Kenyan Security Forces Continue Search For Al Shabab Militants in Nairobi Mall

Authorities say 62 people have been killed

(Reuters)—Somalia's al Shabaab Islamist group said on Tuesday there were "countless dead bodies" in a Kenyan shopping mall as security forces searched for militants still holed up in the complex after a weekend attack that authorities say killed 62 people.

The al Qaeda-linked attackers are believed by Western sources to include Americans and possibly a British woman who may be the widow of a suicide bomber who took part in an attack in London in 2005. Al Shabaab in Somalia rejected suggestions that foreigners were involved.

A burst of gunfire in the early morning broke hours of calm on the fourth day since the militants stormed into the Westgate center in Nairobi during a busy Saturday lunchtime, spraying bullets and lobbing grenades.
