About 1,000 loaded trucks are stranded on the other side of the border, sources said.

Customs authorities and clearing and forwarding agents blamed the slow unloading on lack of warehouse and dumping space.

On an average about 100 trucks enter Bangladesh ever day while only 40 per cent of those goes back after unloading, the sources said.

There has been a snarl-up of loaded trucks on the 12-kilometre road from Bhomra to Basirhat in West Bengal.

The Clearing & Forwarding (C&F) Agents Association has engaged 25 volunteers to help truckers unload their vehicles, but little can be done to ease the situation due to lack of infrastructure facilities, they said.

Trade with India through Bhomra land port increased since its reopening on June 21 after a prolonged closure.

Indian trucks usually carry wheat, maize, tomato, mango, vegetable seeds, pulse and stones.

The C&F association repeatedly appealed to the authorities concerned to build a warehouse and create a 'dumping station' at the land port, but to no effect, they said.

The association also sought permission to setup a private dumping station, but to no response, they said.
