FACTBOX - Key facts on Mumbai gunman Mohammad Ajmal Kasab

(Reuters) - The lone surviving gunman from the Mumbai attacks that killed 166 people, who became India's prime evidence of a Pakistani hand in the three-day siege, made a surprise guilty plea in court on Monday.

Here are some facts about the gunman, Mohammad Ajmal Kasab:

THE ATTACK

* Kasab is one of 10 gunmen who attacked Mumbai in November in a three-day rampage on some of the city's most famous landmarks, including the iconic Taj Mahal hotel.

* Kasab said he was a member of the Lashkar-e-Taiba (LeT), a Pakistan-based militant group on U.S. and Indian terrorist lists.

* The baby-faced gunman was captured wearing a t-shirt emblazoned with the Versace designer label outside one of Mumbai's main train stations.

* He and an accomplice, who was shot dead, had fired AK-47s inside and killed around 50 people. Once captured he became a prime source for Indian investigators.

BACKGROUND

* Kasab told investigators he comes from Faridkot in Pakistan's Punjab region. He said he was recruited by the LeT and given a year of commando training in Pakistan by a former Pakistani military officer. Pakistan initially denied he was their citizen, enraging India.
