 Officials in Bangladesh are now urging all of the country's universities to close down today, a day after violent protests by students over a government job quota system. At least six people have been killed in the protests. Another beach rescue of someone suddenly trapped in the sand. This one on San Diego's Mission Beach. Here's ABC's Rhiannon Alley. Rescue crews say the 16-year-old was digging a six to eight foot hole in the sand when it collapsed.
