Jammu, Sep 18 - There was firing again Friday morning at the Border Security Force (BSF) post on the India-Pakistan border near Jammu where two BSF troopers had been injured Thursday evening.

A senior BSF official told IANS that there was firing again from the Pakistan side on the Nikowal border post, about 30 km west of this winter capital of Jammu and Kashmir.

The firing on the post began Thursday evening when two BSF troopers were injured. The Indian side had retaliated after the first bullet hit the post. 'After last night's lull there was firing again at the same post to which we have again retaliated,' said the official.

He said the BSF was trying to ascertain the source of the firing. It was unclear whether the firing was from militants trying to sneak into India or from Pakistani Rangers, the border guards of that country.

'The preliminary assessment points more to militants trying to infiltrate to this side,' the official said, speaking on condition of anonymity.

He added that the BSF had carried out a check of the three-tiered barbed wire fence from a distance and 'there appears no breach, which scales down the possibility of the infiltration having succeeded.
