Medical staff in Kenya said Saturday that a survivor had been found at the Garissa University College, two days after al-Shabab gunmen killed nearly 150 people at the campus. Kenyan police have so far arrested five people in relation to the incident.

Cynthia Charotich, 19, said, according to the Associated Press (AP), that she had hid inside a large cupboard and covered herself with clothes to avoid facing the militants. She reportedly refused to come out of her hiding place even as some of her classmates emerged after the militants ordered them to do so. She said, according to the AP, that she did not want to come out even when the rescuers called for her, because she was afraid that they also belonged to the militant group.

On Saturday, al-Shabab militants threatened to conduct more attacks in the country, citing the Kenyan government's decision to aid Somalia in its fight against the group. 

“Not only are you condoning your government's oppressive policies by failing to speak out against them, but are reinforcing their policies by electing them … you chose your government out of your own volition so endure the consequences of your actions, for you will bear the full brunt of its follies,” the group reportedly said, in a statement referring to the Kenyan public, adding: “You will, therefore, pay the price with your blood … No amount of precaution or safety measures will be able to guarantee your safety, thwart another attack or prevent another bloodbath.”

Witnesses to Thursday's attack had reportedly said that the militants from the al Qaeda-affiliated group had targeted Christian students, but had let go of the Muslim students at the campus.
