The school in north-eastern Kenya attacked by gunmen earlier is currently under heavy security.
Four men stormed the Abakore high school in Wajir county at 11:00 local time (08:00 GMT) and started firing, several students at the school told the BBC.
Hundreds of students were sitting for their exams at the time.
The attackers hit the administration blocks before the Kenyan police, who were guarding the main school building, responded.
There were no injuries after two gunmen stormed a school in north-eastern Kenya and opened fire on students this morning, reports the Daily Nation, which first broke the story, quoting local police.
The local police chief in Wajir county told the newspaper that the attack on Abaqkorey High School started at 11:00 local time, while students were sitting a history exam.
A manhunt was under way for the two gunmen, who fled into the bush after the attack, police said.
The failed attack was apparently not enough to get the students out of sitting their exam.
They were relocated to a primary school nearby to finish writing their papers, the Daily Nation adds.
