Describing the killing of Indian soldiers by Pakistani troops as "dastardly", Gujarat Chief Minister Narendra Modi Tuesday accused the Centre of being lax in securing the borders.

"Dastardly ambush by Pakistan last night at the Chakan da Bagh area of Poonch leading to death of five Indian soldiers is unacceptable," Modi said in a tweet.

"From China's intrusions to Pakistan's ambushes- UPA government has been absolutely lax in securing the Indian borders. When will Centre wake up?" Modi wrote on the micro-blogging site twitter.

"My heartfelt condolences to the families of the brave soldiers who laid down their lives in Poonch," he tweeted.

Late last night, Pakistani troops entered the Indian territory along the Line of Control in the Poonch sector in Jammu and Kashmir and ambushed a patrol killing five Indian soldiers.

A Subedar and four jawans of the 21 Bihar Unit were killed in the attack which took place at around 2 AM.
