India’s Cabinet on Wednesday called this week’s deadly car explosion in the capital a terror attack carried out by “anti-national forces,” though it did not release any new evidence linked to the blast, Associated Press reported.

Earlier Wednesday, authorities said several suspects had been arrested in the disputed Kashmir region as part of the investigation into the blast Monday near the historic Red Fort monument that killed eight people and injured several others. 

Authorities on Tuesday announced that they were investigating it as possible terrorism — a step that gives investigating authorities broader powers to arrest or detain people. But they have not publicly detailed their evidence, according to Associated Press.
