At least 30 people have died in an explosion in the city of Lahore, Pakistan, according to local police. Scores more are reportedly injured.
The blast struck a big public park in western Lahore, crowded with people enjoying a spring evening, NPR's Philip Reeves reports from ISlamabad.
A police officer told the Associated Press that many families were leaving the park at the time of the explosion.
Reuters reports that, according to a superintendent of police for the area, the casualties included many women and children.
"The park's in the west of Lahore, Pakistan's second largest city — and, historically, the nation's cultural capital," Phil says. "Islamists have attacked it regularly over the years, but for many months Pakistan's army and security services have been carrying out a big military operation against militant groups - especially aimed at the Taliban in the mountains bordering Afghanistan.
"As violence dipped, the people of Pakistan began to relax. Business picked up — and, in Lahore, tourists started to return."
Today's attack, he says, is "another reminder that the conflict in Pakistan is far from over."
