Mount Sinabung continued to spew volcanic ash on Wednesday as thousands of residents remained in temporary shelters fearful of more eruptions.

Authorities have put the area surrounding the 2,460-metre high volcano on alert level three, recommending people not to be within a radius of three kilometres from the crater.

White shrimp (Litopenaeus setiferus) with black gill disease are pictured aboard the boat Billie B just off Otter Island near St. Helena Sound, South Carolina in this September 18, 2006 handout photo obtained by Reuters November 1, 2013. The size of wild shrimp hauls off the southern Atlantic coast have plunged in recent months as a parasite has made it harder for the creatures to breathe, according to state wildlife officials in Georgia and South Carolina. Experts said they believe black gill disease, caused by a tiny parasite, contributed to a die-off of white shrimp between August and October, typically the prime catch season. The disease does not kill shrimp directly but hurts their endurance and makes them more vulnerable to predators.

Solal, a twelve-year-old toreador apprentice of the Nimes bullfighting school, nicknamed Solalito, performs a muleta pass during a beginner's bullfight (becerrada) at the bullring of Bouillargues, near Nimes, October 5, 2013. A muleta is a small cloth attached to a short tapered stick and used by a matador. Since 1983, the French Tauromachy Centre in Nimes has trained some 1,000 youths in the art of bullfighting. Twenty of them have gone on to become professional matadors, facing fighting bulls in the arena. Twice a week, students take courses with a matador to learn the movements and gestures of the bullfighter in the ring, but without an animal present. Students train with calves in the surrounding fields during spring, and regularly participate in beginner's bullfights (becerradas) without killing calves. Solal has been taking courses for three years and Nino, for just a year now. Both are normally enrolled in French public schools, but have one thought in mind - bullfighting. They share a passion linked to the city of Nimes, famous for its ferias and bullring. Picture taken October 5, 2013.
