One person was killed while three were injured after a hand grenade exploded near Haji Limo Goth in Karachi’s Gulshan-i-Iqbal, according to police.

In a statement, Mubina Town Police Station House Officer (SHO) Abdul Sattar said the police and bomb disposal team are at the spot to collect evidence. Further investigation is underway, he added.

The incident was reported soon after JUI-F’s Hafiz Hamdullah survived a gun attack on his convoy in Balochistan. Earlier, at least 28 people were killed after back-to-back blasts hit the province on the eve of general elections.
