Home ministry official UK Bansal told reporters that the explosives appeared to have been kept in a briefcase. The blast took place at around 10.15 am.
The injured have been taken to AIIMS, RML and Safdarjung hospitals. The Delhi Police have cordoned off the area, not far from Parliament and the Prime Minister’s Office. Fire tenders have been rushed to the spot.
Court business is usually heavy on Wednesday which is listed as a Public Interest Litation day when the visitors come to the court in large numbers.
The blast was the second explosion at the high court this year. On May 25, a small explosion that appeared to be a failed car bomb hit the court parking lot.
More details are awaited.
