KOLKATA: Central agencies have written to the Union home ministry alleging that the ruling Trinamool Congress in West Bengal has not only flouted federal policies by facilitating the entry of Rohingyas from Myanmar into the state but also sheltering them.The allegations were made even as the Border Security Force foiled attempts by Rohingyas to enter the country illegally from Bangladesh. In the past two months, the BSF has pushed back at least three teams of 10 to 12 Rohingyas from border points including Swarupnagar and Bongaon in North 24 Parganas district.Security agencies must try to prevent the entry of illegal migrants because it would be very difficult to deport them once they cross over, Union home minister Rajnath Singh had said during a border management meeting in Kolkata with chief ministers of eastern and northeastern states that share borders with Bangladesh.However, West Bengal chief minister Mamata Banerjee was said to have objected to the idea of ‘pushing back’ the Rohingyas and insisted that they should be arrested instead.Some central police agencies have claimed that a few Muslim groups backed by the ruling party have set up camps to shelter Rohingyas in South 24 Parganas district with the patronage of the Trinamool Congress. At Baruipur area in South 24 Parganas, a local NGO has provided makeshift shelter to at least 25 Rohingyas. Some of them hold cards of UNHRC , the UN refugee agency.Some groups are collecting money to provide financial assistance, food and shelter to the Rohingya migrants in West Bengal, allegedly with tacit support of the police and the state government.A senior police official said that the state government acknowledges UNHRC cards and Banerjee on several occasions has maintained that her government will go by UNHRC guidelines on Rohingyas. Over half a million Rohingya refugees have fled violence in Myanmar, according to UNHCR.The reports of the central agencies mention ‘violations’ by Banerjee’s government of the National Democratic Alliance government’s policies on Rohingyas.“The Centre might respond to the reports and the facts soon and act as some of the agencies are finding it difficult to work in a contradictory situation in Bengal. We have reported facts to the concerned authorities,” a senior home ministry official said.Repeated policy disagreements with the Centre and rising instances of political violence between the Trinamool Congress and the Bharatiya Janata Party have led to a situation where Central ministers including Nitin Gadkari have decided not to attend the Bengal Global Business Summit on January 16-17.
