Seven girls, ages 13 to 15, are pregnant after a five-day school trip to their country’s capital city and their parents are being blamed.

The schoolgirls, from the city of Banja Luka, went to the Bosnia and Herzegovina capital, Sarajevo.

Nenad Babici, the national coordinator for reproductive health of the republic, told Inserbia.info that it was discovered that the seven schoolgirls got pregnant on the school trip.

The school in Banja Luka had taken 28 girls to the nation’s capital city for a five-day trip to visit museums and historic sights in the city, ranked among the finest in the world.

Furious parents are demanding to know why there was such a lack of teacher supervision, reported the Daily Mail.

However, Babici blamed parents for not educating their children properly.

He said that early sexual relations later lead to adverse consequences such as infertility, various diseases, miscarriages and premature births.

Senad Mehmedbasic, a Sarajevo gynecologist, said a growing trend of underage pregnancies in Bosnia and Herzegovina is worrying.

“That is the trend of today. But we cannot continue to allow our children to be educated about sex on the street and not in school,” he told Inserbia.info.

Educational institutes and parents, he said, should play a stronger role in providing effective sex education.

“It is obvious that children do not have enough knowledge of health education, so they engage in such activities, not knowing the consequences.

“We have to be more direct in the educational system, it must not be allowed that street teaches children about intimate matters, and that they are later slapped by life.”
