A journalists' group says that the Horn of Africa nation Eritrea leads the world in imposing censorship on the media, followed closely by North Korea, Syria and Iran.

The Committee to Protect Journalists says in a report released Wednesday that 10 countries suppress news coverage by barring international media, putting "dictatorial controls" on domestic media, and imposing other restrictions.

Rounding out the 10 worst censors are Equatorial Guinea, Uzbekistan, Burma which also is known as Myanmar, Saudi Arabia, Cuba and Belarus.

The committee, a nonprofit organization based in New York, works to safeguard press freedom worldwide.

Many of the countries on this year's list also were on the committee's last list, published in 2006.
