Rights Group Says Zimbabwe Troops 'Used Systematic Torture'

Zimbabwe's government has defended its security forces after the country's human rights commission accused them of using systematic torture against protesters.

Also in the programme: Venezuela opposition set for mass protest against Maduro; and the Australian government says it is investigating reports a Chinese-Australian writer has gone missing in China -- we hear from a friend of Yang Hengjun, a blogger and former Chinese diplomat, who has not been heard from since flying from New York to Guangzhou on Saturday.
