An Al-Shabaab attack on the Garissa University college in Kenya that left 148 people dead on Thursday had all the bearings of a cold-blooded terrorist attack, as the gunmen singled out non-Muslims while reportedly laughing and taunting them.
Masked gunmen barged into the college early on Thursday as students were sleeping in their dormitories, and killed those who were not dressed as Muslims or who could not recite verses from the Quran.
'Good Easter Holiday for us'
"We don't fear death, this will be a good Easter holiday for us," the gunmen said in Swahili as they gunned down Christian students, a survivor told AFP.
The attackers asked the students to recite verses of the Quran, and those who could not were shot dead.
Women forced to 'swim in blood'
An aid worker who was among the first to enter the university revealed what three female survivors of the attack told him.
Reuben Nyaora, a clinical officer at the International Rescue Committee, said three women, covered in blood, had picked themselves up from among the dead bodies after lying in blood for hours.
"Then told the women to 'swim in the blood'", Nyaora said, describing how the gunmen were mocking and taunting their victims.
'Come out and live'. Gunmen tricked students and shot them
"If you want to survive, come out. If you want to die, stay inside," the gunmen shouted as they entered the hostel.
Many students fell for this trick, following orders to lie on the ground, only to be shot in their heads by the gunmen, who despite being only four, were able to take down nearly 150 people.
"They were shooting people as they came out; they were making others lie down. They had so many people lying in one place, it was easy killing," a doctor told The New York Times.
Gunmen forced students to call their parents before shooting them
Many students were forced to make calls to their parents on Thursday by the gunmen, who wanted to pass on the message that they were killing their children as retaliation to Kenya's military intervention in Somalia, the breeding ground for Al-Shabaab militants, NYT reported.
They also answered frantic calls from relatives to the students during the siege, telling them that they were shooting their children.
"When our relatives started calling after learning about the siege, the terrorists picked the calls and told the relatives, "We are killing them now. You should know Garissa is for Muslims only," a survivor told Daily Nation.
