"A man can live without food or sleep. He can live when he is thirsty and hungry but when he is insulted, he cannot live. The insult has to be avenged," he reportedly told them.
The Congress, the BSP, the SP and the JD(U) accused Modi of trying to inflame communal passions through Amit Shah while himself wearing the "mask" of development.
The BJP, however, saw nothing wrong in Shah's remarks, according to the party's UP incharge.
"UP government has insulted the people there. It is not a question of Hindus and Muslims. Those who went there for secular tourism, they have insulted the people. Instead of putting balm on the wounds of the victims, they sprinkled salt. Revenge should be taken for this insult," BJP spokesperson Mukhtar Abbas Naqvi said.
