The 130-year-old historical All Saints Church in Peshawar was reopened for worship on Tuesday following repair and cleaning after the deadly blasts on Sunday which killed 83 people and injured about 150 others.
At least 67 victims of the twin blasts were discharged from Lady Reading Hospital after their condition was declared stable.
Meanwhile, the police arrested six suspects on Tuesday for alleged involvement in the church attack.
A special investigation team constituted to probe the incident has revealed that one of the suicide bombers was possibly a young lady aged 20-25 years.
The attack is believed to be the deadliest ever to target the country’s Christian minority.
Christians demonstrated in towns and cities across Pakistan, including Islamabad, Lahore, Karachi and Peshawar, demanding better protection from the authorities.
