Muslim converts are drawn to jihad like moths to a flame.

Nairobi, Kenya (CNN) — Kenyan forces assaulted terrorists in Nairobi’s Westgate Shopping Mall on Monday afternoon, killing two and claiming to take control of all floors of the building despite the continued presence of gunmen inside.

It was unclear if any hostages remained inside the building, but authorities expect the number to be “very, very minimal,” if any remain, Interior Minister Joseph Ole Lenku said at a news briefing. Most had already been evacuated, he said Monday, the third day of the siege.

At least 69 people have died since the siege began Saturday, authorities said.

Dark smoke seen rising from the building after the assault began was from fires set by the gunmen to distract forces from the assault, Lenku said. […]

While senior Kenyan intelligence sources told CNN on Monday that surveillance video from inside the mall appears to show a white woman taking part in the attack, Lenku told reporters that all of the attackers were men.

Some of the terrorists apparently dressed as women, he said.

The sources say that the woman is actively involved in the attacks and that they believe she is British.

The report came after earlier speculation that the Al-Shabaab-affiliated “White Widow,” Samantha Lewthwaite, may have been involved in the attack.

Lewthwaite’s husband, Germaine Lindsey, was one of the suicide bombers killed in the 2005 attack on London’s transportation system. His Buckinghamshire-born widow is wanted by Kenyan authorities for her alleged role as an Al-Shabaab and al Qaeda-linked financier.
