Demonstrations, according to numerous sources, have been held in the port town of Massawa, Agordat and in the capital city Asmara.

According to Eritrean opposition sites, the demonstrations began after the closure by the government of an Islamic school.
An official of the Red Sea Afar Democratic Organization -- an Eritrean opposition group operating in neighboring Ethiopia -- has put forth the number of at least 28 deaths due to crackdown by security forces since Tuesday. This number could not be independently verified as the country remains essentially closed off.
Nesredin Ahmad, the liaison officer of the Red Sea Afar Democratic Organization, also told Anadolu Agency, again citing connections in Asmara, that hundreds had been injured.
