Dozens killed in attack on Easter celebrations in Lahore

Dozens of families, including women and children were at the crowded park where Christians had gone to celebrate Easter, according to officials.

Lahore officials confirmed the attack however stated "the nature of the blast is not clear."

Pakistan has witnessed widespread instability and chaos as militants from extremists groups routinely carry out attacks against the government.

At least 16 people were killed when another attack ripped through a bus in Peshawar earlier this month.

However, Sunday's attack in the otherwise peaceful cultural city of Lahore comes as a surprise.

Levels of violence in the country have fallen since 2014 when the army launched a major offensive against the Taliban and al-Qaeda in their respective strongholds.

No group has claimed Sunday's attack.
