A second successive bomb exploded Wednesday near a Shia Imambargah in Karachi where an explosion about half an hour earlier had killed at least two people.
The second explosion ripped close to the same location as police personnel and TV reporters were present at the site of the first blast.
The nature of the second blast and resulting casualties could not be ascertained as yet.
About half an hour earlier, a bomb planted in a motorcycle ripped through the neighbourhood near the Imambargah in Orangi Town area, killing at least two people and injuring three, police said.
“We have also found a body which might have been a suicide bomber, although it can not be confirmed yet,” DIG West Karachi Javed Odho had said, speaking about the first blast.
