The Japanese embassy said it has received an e-mail warning of a bomb planted in a New Delhi market, and has warned its citizens to stay away from crowded public places. Nearly 30 explosions shook two Indian cities over the weekend, and 19 unexploded bombs have since been found in a western Indian city. Japan's embassy said in a notice on its Web site it has been warned of a bomb planted in the capital's popular Sarojini Nagar market. The notice urges Japanese citizens "to stay away from public places where many people gather, such as stations, markets (including Sarojini Nagar), bus stops and religious institutions." Sarojini Nagar was one of three New Delhi markets bombed in October 2005. Those blasts killed 62 people.
