A Mexican protester disrupted the Nobel Peace Prize ceremony for Malala Yousafzai Wednesday in Oslo, Norway, when he unfurled the Mexican flag and said, “Please Malala … Mexico,” CNN Mexico reported. It’s unclear what the man was referring to because he was quickly escorted out of the ceremony by security.

The outburst came during a time of outrage in Mexico over the disappearance of 43 students, who some Mexicans believe were killed by corrupt Mexican policemen at the request of corrupt Mexican politicians. The Mexican government is facing pressure by citizen protests over the slow response in investigating the September incident.

The man may have been alluding to the disappearances of the students in Iguala, Mexico, since Malala won the Nobel Peace Prize for her advocacy in fighting for women’s education. Malala, 17, was 15 when she was shot by the Taliban in her native Pakistan for refusing to stop attending school.

The Mexican students, who were from a left-wing college and training to be teachers, were believed to have been detained by corrupt police and then had their bodies burned by a drug gang, Reuters reported Sunday. The mayor of Iguala and his wife were among 80 people detained in a probe of the incident after the couple were accused of trying to kick the students out of his town for staging a protest.
