Nigerian firefighters battled two fires that broke out almost simultaneously Tuesday at a busy market in central Lagos, the country’s largest city and commercial center. Balogun Market, where the fires erupted, is one of Nigeria’s largest textile markets. The fire started in the morning and became a major blaze by midday, with firefighters trying to keep the flames from spreading. The Balogun market sprawls across many blocks on Lagos Island. It is well known as one of the best places in Lagos to buy colorful Nigerian fabrics, apparel and shoes. Fires and other disasters are frequent on Lagos Island where the Balogun market is located. In March, at least 20 people, most of them schoolchildren, died with the collapse of a three-story building housing a school, residential apartments and shops.
