There were no security lapses as all the necessary measures had been taken for the BJP rally, Kumar told reporters here.
Five people were killed and 66 injured in six serial blasts near the venue of Gujarat Chief Minister Narendra Modi's rally in the state capital today.
Defending the arrangements, Kumar said "There were no intelligence inputs either from the Centre or from the state. Whatever was possible to do for this kind of a programme, the administration had done.
But, despite the arrangements, blasts had taken place, which was matter of great concern for the state, Kumar said.
"It was a lesson for us as, despite the bandobast, this happened. It is a matter of great concern for all of us and a challenge for the entire state," he said.
The serial blasts were an attempt to threaten the law and order situation in the state and it cannot be a coincidence that they occurred on the day of the rally, Kumar averred.
Appealing for peace, Kumar said, "Some elements are trying to create trouble. We have to face (them) unitedly.
