Islamabad: Pakistan on Monday mourned the dead in the deadly suicide attacks on two churches in Lahore that killed 15 people, as Christians took to the streets to denounce the ghastly massacre.
Provincial governments declared Monday a day of mourning. All missionary schools and colleges were shut across the country, officials and the media reported.
Security was stepped up in churches and missionary institutions while patrolling by police and Pakistan Rangers were enhanced, Dunya TV quoted officials as saying.
Prayer ceremonies were held in churches across Pakistan on Monday.
Two powerful explosions on Sunday rocked the Catholic Church and the Christ Church in Lahore's Youhanabad area, home to the country's biggest Christian population.
The churches are separated by half a kilometre.
Jamatul Ahrar, an offshoot of the Pakistan Tehreek-e-Taliban, claimed responsibility for the attack which took place as large crowds were in the area to attend the Sunday prayers.
Violent protests erupted at the site after the blasts, with a 4,000-strong Christian mob armed with clubs smashing vehicles and setting fire to two suspected terrorists.
Television footage showed dozens of stick-wielding men ransacking the city's metro bus terminal. Protesters also clashed with the police.
Prime Minister Nawaz Sharif said the anger and grief of the Christian community in the wake of the terror attack strengthened the government's resolve to counter terrorism.
"Our Christian community has rendered invaluable services to the motherland, particularly in the social sector, and we consider them as our honour and pride," Sharif said.
