Ethnic hatred is now considered as the most likely motive behind a Moscow market explosion, which killed 10 people and injured 55 others, a city prosecutor said on Tuesday.

City Prosecutor Yury Syomin was quoted by Russia's Interfax news agency as saying that "It is one of the theories, and one that has become dominant."

Three suspects, all under 25 years old, have been detained as part of the investigation process, the prosecutor said.

"The investigation has no information regarding the suspects' possible affiliation with any formal organizations or groups. The detainees do not have any party IDs," he said.

Eight people, including two children, were killed when the explosion hit the Eurasian section of Cherkizovsky market in northeast Moscow on Monday morning, and two others died at hospital.

The bomb was a home-made device and contained more than 1 kg of TNT explosive, Syomin said.

However, Russian Prosecutor General Yury Chaika told reporters that two theories -- terrorist attack and gangland feud -- are being looked into by investigators probing the case.

The Interfax reported that Chaika said in Tajikistan's capital of Dushanbe on Tuesday that "These are the main theories at the moment. Two people have been detained as part of the investigation."
