Garissa (Kenya), April 4: Somali militants Al-Shabab has threatened to carry out more attacks in Kenya, media reported on Saturday.
At least 148 people including 142 students, three policemen and three soldiers were killed when masked Somali militants stormed the university campus on Thursday.
For Kenya, Thursday's terrorist attack was the deadliest since the bombing of the US Embassy in Nairobi in 1998 that left 200 people dead.
In a statement issued on Saturday, the group warned Kenyans that their cities will "run red with blood", Al Jazeera reported.
"No amount of precaution or safety measures will be able to guarantee your safety, thwart another attack or prevent another bloodbath from occurring in your cities," the statement said.
Four al-Shabab fighters stormed the Garissa University College campus in what appeared to be an extensively planned out attack, which the group says was to avenge Kenya's involvement in Somalia.
Surviving students have been taken to a military camp, waiting to be bussed home as the university has been indefinitely closed.
Al-Shabab has carried out a number of attacks in Kenya since 2011, when Kenyan troops were sent to Somalia to help fight the militant group there.
The deadliest attack targeted the Westgate shopping centre in Nairobi in September 2013, when 67 people were killed. Al-Shabab is fighting to create an Islamic state in Somalia and is banned as a terrorist group by both the US and Britain.
