Hundreds of angry mourners mobbed Taiwan leader Ma Ying-jeou on Sunday as he attended the funeral service for a young soldier who died after allegedly being abused by his officers.

Protestors, including relatives and sympathizers, shouted "We want truth!" as Ma, protected by security guards, made his way to the funeral site at the soldier's home in the central city of Taichung.

The service was held a day after more than 100,000 people took to the streets of Taipei to protest the death of Cpl Hung Chung-chiu.
