In just over a week, thirteen journalists have been arrested.

Two more journalists have been seized in Addis Ababa, bringing the total number of journalists and media workers imprisoned in Ethiopia to 13 since last week.

Some have seen the action as a crackdown on critical voices.

The arrests have occurred in tandem with the commencement of a "law enforcement operation" in the Amhara region, which has resulted in the detention of thousands of people.

The Committee to Protect Journalists, a Washington-based advocacy group, named Ethiopia as one of the worst jailers of journalists last year.

In just over a week, more than a dozen journalists and media workers have been imprisoned in a new round of arrests.

But journalists aren't the only ones who are being targeted.

Authorities in Amhara, Ethiopia's second most populated province, announced on Monday that they had imprisoned more than 4,500 people.

Activists, soldiers and militiamen, and academics were among them. The arrests have continued since then.

Although Amhara's representative informed the BBC that he did not have the most recent data, the security office told local media that up to 2,000 people had been held in addition.

It comes amid fears that the operation's continuation could exacerbate tensions - and potentially violence - in a country already riven by civil war and ethnic strife.
