According to the BBC, bad weather, murky water and strong currents are hampering the search for survivors of the South Korean ferry disaster. Emergency services are still searching for 287 people missing after the vessel sank. Officials say 179 people have been rescued. Most of the passengers were pupils at the same high school. South Korea's president visited the wreck and urged rescuers to "hurry". Park Geun-hye said that time was running out and that every minute and every second was critical.
