Frankfurt airport workers found a body in the landing gear of a Lufthansa plane after it arrived from Tehran

• Airport workers found a body in the landing gear of a Lufthansa plane on Thursday, police told CNN.
• The Airbus jet had arrived from the Iranian capital of Tehran, police said.

Airport workers found a dead body in the undercarriage of a Lufthansa jet that had arrived from Iran on Thursday morning, reports say.

Employees at Frankfurt airport found the body of a male in the landing gear of a Lufthansa jet that had arrived from Tehran during a routine maintenance check at 5:30 a.m. local time, police told CNN.

Bild, which first reported the news, said the workers found a mask and an oxygen tank beside the body, per police information.

"We can confirm that during the routine check of a Lufthansa Airbus A340-300 after landing in Frankfurt yesterday, a dead body was discovered in the aircraft's landing gear bay," a Lufthansa spokesperson told CNN.

"The responsible authorities are currently on site to investigate the background together with experts from the company. We ask for your understanding that we cannot provide any further information against the background of the ongoing investigation."

The German press agency DPA said that a flight due to operate on Friday from Tehran to Frankfurt was canceled, per Deutsche Welle. Lufthansa scheduling information indicates that it and another flight on Saturday were canceled, but the service was expected to resume on Sunday.

The discovery follows weeks of protests in Iran following the death of 22-year-old Mahsa Amini in police custody, after she was arrested for not wearing her hijab correctly, according to BBC News.

Germany's foreign minister, Annalena Baerbock, said on Thursday that Berlin would begin imposing entry restrictions on Iranian nationals in response to the worsening battle between the state and citizens over human rights.

Lufthansa didn't immediately respond to Insider's request for comment.
