Sending a strong message on women's security, Modi said politicians should stop commenting frivolously on such incidents.
"I want to appeal to the politicians of the country, stop this psychological analysis of incidents of rape. It does not behove of you," Modi said.
"They are playing with the dignity of our mothers and sisters. Such a commentary is not appropriate at political level. The respect and security of women should be the concern of all 125 crore Indians," he said
Samajwadi Party chief Mulayam Singh Yadav is among leaders who have commented on the issue - saying "boys will make mistakes" - drawing wide criticism.
On the farm sector, Modi said proper management of agriculture products through modern technology can help control food inflation, adding that there is adequate availability of food products in the country.
"There is enough food in the country. What is required is proper management," Modi said.
He said efforts should be made to gather "real-time data" of agricultural products that would help regulators take the required action to manage prices.
