Somalia's Islamic extremist group al-Shabab warned Saturday of more attacks in Kenya like the assault on Garissa University College that killed 148 people.
"Kenyan cities will run red with blood," said al-Shabab according to the SITE intelligence monitoring group.
The Islamic militants said the attack on Garissa college was in retaliation for killings carried out by Kenyan troops fighting the rebels in Somalia.

"No amount of precaution or safety measures will be able to guarantee your safety, thwart another attack or prevent another bloodbath," said al-Shabab.
Following the extremists' threats, Kenyan President Uhuru Kenyatta vowed to take harsh measures against the Islamic militants.
