SRINAGAR (Reuters) - Indian border guards said their troops came under fire from Pakistan on Wednesday, a day before the two nuclear-armed neighbours are set for the first official talks since the 2008 Mumbai attacks.

"The firing from across the border started early morning. A BSF (Border Security Force) personnel was injured," Vinod Sharma, a spokesman for the border guards, told Reuters.

Pakistan denied any shooting by its troops.

"Our troops were not involved in any firing. There may be some problem on their own side," said Nadeem Raza, a spokesman for Pakistan's paramilitary Rangers.

Area commanders from the two sides were due to meet later in the day to settle the matter, Raza said.

The shooting took place in the Samba area of south Kashmir, the Himalayan region at the core of decades of hostility between India and Pakistan and the cause of two of their three wars since independence from British rule in 1947.

The foreign secretaries of the two countries will meet on Thursday for talks that could eventually pave the way for the resumption of the formal peace process broken off after the 2008 Mumbai strike that killed 166 people.

There has been a spate of clashes in the past few months along the Line of Control, the de facto border dividing mostly Muslim Kashmir between Hindu-majority India and Pakistan, an Islamic nation.
