"Can 26/11 happen again? Yes, any time," warned retired Major General V.K. Datta, India's most decorated army officer, referring to the November 26 attacks that killed 166 people and injured more than 300 last year.
The acting head of Maharashtra state police, A.N. Roy, said greater vigilance and better counter-terrorism measures were vital because Mumbai, the state capital, played a key role in India's economy.
His counterpart at Mumbai police, D. Sivanandan, said improvements have been made since the force was found lacking training, equipment and manpower against the 10 heavily armed Islamist gunmen who stormed the city 12 months ago.
