Banda Aceh – Officials say a German working for the Red Cross has been shot by men on a motorcycle in Indonesia's Aceh province.

Police say Erhard Bauer, 50, was shot Thursday in the arm and stomach. The motive is unknown. Red Cross spokeswoman Svenja Koch says Bauer was flown to Singapore for treatment. She could not say if the injuries were life threatening.

Aceh Gov. Irwandi Yusuf visited Bauer before he was evacuated but declined to comment to reporters.

Aceh, which was hit by the Indian Ocean tsunami nearly five years ago, was the scene of a string of shootings ahead of elections in April, but it has been months since an incident.
