South Waziristan: Dozens of terrorists entered a police station in Pakistan's   Wana town on Tuesday and escaped after looting arms and ammunition, media reports said on Wednesday.

Around 1am, militants armed with rocket launchers and heavy weapons forced their way into the police station, according to a cop, Rehman Wazir, who was inside at the time of the attack, reports Dawn News.

He told the newspaper that around 50 militants entered the station after blowing up the front gate.

Heavily outnumbered in front of militants, around 20 policemen, including the station house officer, resisted for some time but were later taken hostage, another police official told the newspaper.

Pakistani politician Mohsin Dawar shared a video on social media where the attack on the police station could be seen.

"A police station in Wana, South Waziristan was attacked by terrorists earlier in the morning today. This is the 4th major attack in Pakhtunkhwa in the last 3 days. The intensity and frequency of attacks in Pakhtunkhwa has continued to increase," he tweeted sharing the video.
