India's Prime Minister, Manmohan Singh has vowed to take whatever measures are necessary to track down those responsible for the Mumbai attacks.

He said the perpetrators were based outside the country and India would not tolerate neighbours who provide a haven to militants targeting it.

Gunmen targeted at least 16 locations in Mumbai yesterday, killing at least 107 people and injuring more than 300.

An Indian General said 10 to 12 gunmen were still holed up at three sites.
