New Delhi (PTI): "With every blast we are gaining experience," says Union Home Secretary Madhukar Gupta.

"We have been observing that these kinds (of blasts) are happening in cities across (the country) in each incident you learn, gain experiences...," Gupta told reporters today after attending a review meeting chaired by Union Home Minister Shivraj Patil here after last evening's serial blasts.

He said that now the Ministry will come out with a list of 'do's and dont's' to "fill gaps".

"...At this point of time investigation is going on and everybody should focus on that investigation and in such a way that nothing should hamper the probe," he said.
