"Security and alertness needs to be enhanced. This was definitely a terror attack," Rijju said, as quoted by The Times of India.
On Sunday evening, an improvised explosive device (IED) detonated on a crowded street in Bengaluru, the capital of India's Karnataka State.
According to the Times of India, the local Karnataka government will hold a high-level meeting to consider responses to the explosion.
In November, The Guardian newspaper, citing Indian security officials, reported that India was facing terrorist threats. The sources told the newspaper that the withdrawal of US forces from Afghanistan, the weakness of the newly elected government in Pakistan as well as the rise of the Islamic state (IS) militant group were among the reasons for an increase in the possibility of terror attacks.
