Indian police say they have found 19 explosive devices in the southern city of Hyderabad a day after two bombings there killed at least 42 people and wounded more than 60 others.
Police say the unexploded bombs, fitted with timers, were planted at public places such as cinema houses and bus stops across Hyderabad, the capital of Andhra Pradesh state.
Authorities are searching for those responsible for the bombings late Saturday of a busy restaurant and an amusement park. Police say several people have been detained for questioning.
The chief minister of Andhra Pradesh Y. S. Rajasekhara Reddy says "available information" suggests that terrorists based in Pakistan and Bangladesh are responsible for the bombings, as well as a bomb attack in a city mosque that killed 11 people in May.
The chief minister of Andhra Pradesh says the government will offer about 12-thousand dollars to the families of those killed in Saturday's blasts.
Hyderabad is one of India's largest cities and a center of the nation's information technology industry. It has a large Muslim minority, and a history of clashes between Muslims and Hindus.
India has blamed Islamic militant groups based in Pakistan, such as Lashkar-e-Taiba, for attacks in New Delhi and Mumbai in recent years. Security experts say these groups use local Muslims to carry out the attacks.
