Gilgit-Baltistan Police (a northern Pakistan territory bordering China and Afghanistan) have detained 15 suspects during a sweeping security operation following an ambush that killed three officers and wounded five others, including a senior police official. The attack targeted a police team returning from an anti-poppy cultivation drive in the Thore Valley near Chilas, with authorities saying militants sought to keep the remote, mountainous area free from law enforcement presence. Police say the operation will continue until all perpetrators are brought to justice, while security across Gilgit city has been raised to high alert following additional threats against police installations.
