An explosion near a park in the Pakistani city of Lahore killed at least 50 people Sunday and injured dozens more, local officials reported.
The blast occurred Sunday evening at the main gate to Gulshan-e-Iqbal park.
Many Pakistani Christians had gathered in the park to celebrate Easter after church services. An injured woman is carried off by medics.
There is speculation among local authorities that the blast was intended to target them, the BBC reported.
Security officials told the Dawn newspaper the blast was the work of a suicide bomber, whose head had been recovered.
On Twitter, Pakistani journalist Omar Quraishi shared photos purporting to show the chaotic aftermath of the blast.
Facebook turned on its emergency check-in services to enable those in the area or who might know someone in the area to quickly let their friends and family know they are safe.
However, an error on the site caused alerts to be sent out to people all over the world, regardless of whether or not they had been to or knew people in Pakistan.
Punjab, of which Lahore is the capital, is Pakistan's political center, as well as the largest and wealthiest province in the country. It is where Prime Minister Nawaz Sharif resides and functions.
Earlier on Sunday, the prime minister had shared a post on Facebook to celebrate Easter for
Christians all over the world and particularly the Christian community in Pakistan."
"We are committed to ensure that all the communities in Pakistan enjoy equal rights irrespective of their beliefs," he wrote. "We are determined to work for the uplift and welfare of all minorities so that they can contribute to the progress and development of the country like their Muslim brethren."
No group has yet claimed responsibility for the blast, but the Pakistani Taliban regularly launches terror attacks and bombings inside the country.
