*Eritrea  travel warning* http://travel.state.gov/travel/cis_pa_tw/tw/tw_5359.html The US Department of State (DOS) issued a Travel Warning<http://travel.state.gov/travel/cis_pa_tw/tw/tw_5359.html> regarding Eritrea. In addition to cautioning persons about traveling in that nation, it strongly advises US citizens to avoid the Southern Red Sea region (including the port of Assab). US citizens on ship and sailing vessels are strongly advised not to attempt to dock in Eritrean ports or travel through Eritrean waters. In December 2010, a British ship attempting to refuel in Massawa was detained by Eritrean authorities and its crew of four has not been released. (2/27/11).
