KEY POINTS:
HYDERABAD - Investigators were pursuing leads yesterday from materials used to make bombs that killed 40 people in a southern Indian city, while Hindu nationalists called a strike to protest against the attacks blamed on Islamic militants.
The twin blasts on Sunday in Hyderabad, an emerging information technology centre, wounded about 80 people and authorities suspect Islamic militant groups based in Pakistan or Bangladesh.
No arrests have been made so far but city police chief Balwinder Singh said people had been questioned.
He said a chemical substance called "neogel" had been used to make the bombs.
"It is used for blasting and mining purposes. It is produced under restriction in Nagpur," he said, referring to the central Indian city in the neighbouring state of Maharashtra, which is about 350km north of Hyderabad.
