Dhaka - A young Bangladeshi man was gunned down by suspected Indian security forces near the India-Bangladesh border amid mounting tension along the common frontier of the two neighbours, local police said Monday. 

Omar Shareef, chief of Benapole police station in north-western Bangladesh, claimed the body also bore marks of multiple wounds. 

With the latest casualty, the number of people killed since Friday in border violence rose to seven. 

Bangladeshi officials said the Indian Border Security Force (BSF) has taken up an aggressive posture since the paramilitary outfit was ordered to shoot at sight any person near the frontier after sunset. 

At least 73 Bangladeshi civilians were killed allegedly by BSF in the past six months, official records said. 

"India is our friendly neighbour and such a huge number of killing of civilians is unacceptable," said Bangladesh Foreign Secretary Touhid Hossian, returning home after an annual consultation meeting with Indian Foreign Secretary Shiv Shankar Menon in New Delhi. 

The BSF shot dead two soldiers of the Bangladesh Rifles (BDR) in a border skirmish near Chapai-Nawabganj district in northern Bangladesh on Friday, whipping up tension along the frontier. 

Two Bangladeshi nationals were also killed during the midnight shootout. 

The Bangladesh government has lodged a strong protest with Indian authorities over the killings. 

Relations between the two South Asian countries soured when the Indian authorities stopped delivering rice to Bangladesh at the height of a food crisis in June 

Bilateral ties also suffered due to Bangladesh's refusal to give transit rights to India. 

India and Bangladesh share over 4,000 kilometres of porous land boundary, which is plagued by cross-border crimes including gun running and trafficking of women and children. 

India also complains of illegal migrants coming from Bangladesh and settling down. (dpa)
