Prime Minister Manmohan Singh on Tuesday described as "complex" the issue relating to the demands for a tough anti-terror law in the wake of recent bomb explosions in the country.
"It is quite a complex issue. It is not the question of having a law alone," he told journalists accompanying him to New York for the UN General Assembly.
Singh said he had not reached a conclusion yet on having a new anti-terror law.
A committee of officials has been asked to look into the recommendations of the Administrative Reforms Commission (ARC) regarding a legislation to deal with terror, he said.
When pointed out that more states were desiring a separate anti-terror law, Singh said he would not like to be dragged into the debate related to Centre-state relations.
He, however, said the Centre has the responsibility to decide whether or not a state required an anti-terror law.
Singh's comments came in the backdrop of Gujarat Chief Minister Narendra Modi's plea to the Centre not to keep the anti-terror law GUJCOCA pending. The law is still awaiting clearance of the Centre.
