Death toll from Mumbai triple bombing rises to 20

The death toll from last week's triple bomb blasts in India's financial hub has risen to 20 as Mumbai police pursue leads gathered from the three blast sites.

Police inspector Madhe says the man succumbed to severe burn injuries he sustained when a bomb went off in the crowded Jhaveri Bazaar in Mumbai.

Mumbai's anti-terrorism squad today was examining footage from closed circuit cameras installed at the bomb sites as police stepped up the hunt for the perpetrators of the July 13 attack.

Suspicion has fallen on the Indian Mujahideen, an Islamic militant group linked to Pakistan's Lashkar-e-Taiba that has claimed past terrorist attacks using similar explosives.

Police have fanned out to at least 10 cities to question Mujahideen activists.
