NAIROBI, Kenya (AP) — Hundreds of mourners gathered on Friday in Kenya’s central town of Gilgil for a memorial service to honor the lives of 16 students who died in a fire at a girls school last month that police said was caused by arson. Authorities have arrested nine suspects.

The remains of the girls, who were students at Utumishi Girls Academy, were placed in white coffins adorned with flowers and topped with their portraits. The coffins were lined up in front of their families, schoolmates, community members and local leaders, who called for justice.

The nine accused girls, who were students at the school, remain in police custody, with interrogations revealing that the May 28 blaze was started by lighting a mattress at the dormitory’s exit using a matchstick and paraffin. No motive has been revealed so far.

During the memorial service, hundreds of students from Utumishi Girls Academy sang a somber hymn declaring that all shall be well. One of the presiding officials reminisced about being a victim of Kenya’s deadliest school fire in 2001, when 67 boys died in a dormitory blaze in Machakos County in eastern Kenya.

Mourners called for accountability and justice as dozens of schools have closed in recent days because of student unrest. The Kenya Red Cross said that it had responded to 37 school fires since the beginning of the year.

School fires are common in Kenya, with some linked to arson attacks by students protesting disciplinary measures or scheduled examinations, while others are caused by electrical faults.

Congested dormitories, a lack of emergency exits and insufficient firefighting equipment have often contributed to loss of life and extensive damage.

Last month, Kenya's Education Ministry suspended the principal of Utumishi Girls Academy for failing to comply with school fire safety regulations. The ministry also said that it had closed more than 300 schools following a 2024 fire tragedy that killed 21 boys in central Kenya.

During the Friday memorial service attended by Kenyan first lady Rachel Ruto, the presiding bishop questioned how much longer Kenyan children and families would continue to suffer from school fires.

The school captain, Abigael Wanjiku, eulogized the girls as “friends, study partners, teammates and companions.”

“The pain of losing them is one that we will carry for a long time,” she said.

A mother representing the parents broke down in tears during her speech as she called for accountability and justice, while reassuring the surviving students that ensuring their safety remained a priority.
