Detained protesters in Cuba could get up to 30 years in prison as they face the largest and most punitive mass trials on the island since the early years of the revolution.

Prosecutors this week put on trial more than 60 citizens charged with crimes, including sedition, for taking part in demonstrations against the country's economic crisis over the summer, said human rights activists and relatives of those detained.

Those being prosecuted include at least five minors as young as 16. They are among the more than 620 detainees who have faced or are slated to face trial for joining the biggest outburst of popular discontent against the Communist government since it took power in 1959.
