Ban expressed solidarity with the government and people of India and reiterated "his firm stance that there is no justification for indiscriminate violence against civilians," deputy UN spokesman Eduardo del Buey said.
The Secretary-General "hopes that the perpetrators will be brought to justice," Buey said.
In a separate statement read by the current UN Security Council President, Lebanon's envoy to the UN Nawaf Salam, the UNSC also "condemned in the strongest terms" the terrorist attack that killed 11 people and left over 60 injured.
"The members of the Security Council reaffirmed that terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security, and that any acts of terrorism are criminal and unjustifiable, regardless of their motivation, wherever, whenever and by whomsoever committed," the 15-member council said.
Expressing sympathy and condolences to families and victims of the "heinous act", the Security Council said it is determined to combat all forms of terrorism.
