A court in Taipei has jailed eight Taiwanese soldiers for spying on behalf of China in exchange for money.

Retired military officers bribed active duty soldiers with as much as 700,000 Taiwan dollars ($21,900; £16,700) to join a spy network, the court found.

One of the men, who was believed to be key to recruiting soldiers, got a 13-year sentence, the longest in the group.

One of the recruits, a lieutenant-colonel, was handed nine years for planning to defect to China by flying a helicopter, while another shot an instructional video about surrendering to China in the event of war.
