Some patients who were airlifted from Garissa have now arrived for treatment as Kenyatta National Hospital in the capital, Nairobi.
The head of the African Union mission in Somalia says he has been "shaken" by the attack in Garissa.
"If you attack a military, it's an equal battle, but if you go after students, who are learning, who are preparing for the future of Africa, it's different. Al-Shabab has no accountability... Because of who they have targeted today - I'm a father myself - I am shaken," Maman Sidikou told BBC Focus On Africa's James Copnall, external.
Kenya's Ministry of Interior tweets, external: "#GarissaAttack update: Two terrorists have been neutralised in the ongoing operation. Security agencies intensify rescue operation."

We've got more details on the man the Kenyan government calls the mastermind of the Garissa University College attack.
A BBC Somali Service reporter says that Mohamed Kuno was a headmaster at a madrassa, or Islamic school, in Garissa before he quit in 2007 to join the now-defunct Union of Islamic Courts (UIC) Somalia.
When the UIC split, Mr Kuno joined al-Shabab and became a high-ranking official. Recently he has been involved in running al-Shabab's activities in Kenya. He goes by the nickname "Dulyadeyn", which in Somali means the long-armed one.
The Kenya government has named Mohamed Kuno as the mastermind of the Garissa University College attack.
Kenya's Cabinet Secretary for Internal Security Joseph Nkaiserry placed a $53,000 (£35,700) bounty on Mr Kuno.

There have been several recent al-Shabab attacks in north-eastern Kenya - and as in the Westgate mall siege of 2013 - Muslims and non-Muslims have been separated.
A survivor of a bus that was attacked in November told the BBC that the militants asked passengers to recite from the Koran - those who could not quote from the Muslim religious text were killed.
When al-Shabab called the BBC earlier, its spokesman said the group was behind the attack on Garissa University College because it considers it a non-Muslim institution on Muslim ground.
