Authorities in China are investigating a suicide bombing after a man blew himself up in a government office.

After being paralysed in an accident at work, he claimed he'd been denied proper compensation.

The case highlights growing tensions in Chinese society ahead of a major handover of power.

At least six government officials were injured in the blast in Shandong province.

The BBC's correspondent, Martin Patience, has visited the man's village.
