Muslim passengers helped shield non-Muslim passengers, some of them Christians, during a terrorist attack on a bus in Northern Kenya on Monday, according to multiple published reports.

Daily Nation, a Kenyan newspaper, reported a bus traveling from the Kenyan capital of Nairobi to Mandera was attacked at about 7 a.m. local time by gunmen believed to be tied to Al-Shabaab.

The Associated Press reported 60 passengers were on the bus when the gunmen stopped it in Papa City, and that some of the Muslim passengers helped some of the non-Muslim passengers put on Islamic apparel, such as head scarves, to help mask their identities from the terrorists.

The bus passengers might have been recalling a similar attack that took place last November.

Al-Jazeera reported that Al-Shabaab militants stopped a bus near Mandera, singled out 28 non-Muslims aboard, and killed them. The BBC also reported that Al-Shabaab militants singled out Christians when they shot and killed about 150 people at Kenya’s Garissa University in April.

The quick-thinking passengers ensured that a similar scene wouldn’t take place this time.

A local government official told Daily Nation that the militants reportedly asked the passengers to exit the bus and separate themselves into two groups: Muslims and non-Muslims. The official told the newspaper the gunmen “were trying to identify who were Christians and who were not.”

But the passengers refused to divide themselves. Mandera Governor Ali Roba told Daily Nation that the passengers insisted the gunmen “should kill them together or leave them alone.”

According to the Associated Press, the gunmen ordered everyone back on the bus after a Muslim passenger told them that the bus had a police escort that was due to arrive on the scene shortly.

Two people were killed and three were injured in the attacks, Roba wrote on his Twitter page. The governor said the militants also attacked a truck.
