KARACHI: At least 30 people were injured in a grenade attack on Kashmir Solidarity Rally organised by Jamaat-e-Islami (JI) in Karachi's Gulshan-e-Iqbal area on Wednesday, as Pakistan marked the first anniversary of India’s revocation of Kashmir’s semi-autonomy.

The wounded were rushed to different hospitals, where one was in a critical condition, an official from the provincial health department said.

According to police a grenade was lobbed in the rally, causing several casualties.
