Bomb Explodes in Pakistani Church

A bomb exploded earlier this week inside a Roman Catholic church in Karachi, Pakistan, causing an injury and destruction.

Police said the explosion Tuesday occurred at St. Patrick’s Cathedral in southern Karachi minutes after the congregation celebrated Mass. Most people had departed when the bomb went off, witnesses said. One woman was reported wounded.

No group has claimed responsibility for the explosion, but police have responded to the attack with tightened security at churches and other Christian properties in the city.

“We are investigating . . . but so far we have no clues,” said police commissioner Shafique Paracha.

Religious minorities in the overwhelmingly Muslim country often complain about attacks and persecution by extremist Muslim groups. Dozens of Christians have died in recent years in attacks by Muslim extremists.
