Afterwards, one of them pulled a knife and another threw a petrol bomb, which started a fire, leaving left two officers injured but none dead.

After being shot, the police recovered two bullet-proof jackets and an unused petrol bomb, from the dead suspects

Although It was not initially clear who was behind the attack, it was later attributed to Islamist group, Al-shabaab, who have staged numerous attacks in Kenya.

According to the police, while being shot, the women were heard reciting the Arabic slogan, ‘Allahu Akbar’ while claiming allegiance to Al-shabaab.

“Even as police fired bullets at them, they did not run. They shouted until bullets felled them down,” an officer said.

Two separate police sources have also confirmed that a woman who had housed the suspects the night before the attack, had been arrested.

The Somali-based group was said to have been targeting Kenya since 2011, when Kenyan troops were deployed to rid Somalia of the militants.
