UN Secretary General Ban Ki-moon Sunday ‘strongly’ condemned the bomb blast in Quetta, calling on authorities there to act quickly against those responsible, his spokesman Martin Nesirky said.

Noting that this is the second attack against the minority Shias community in Quetta in the last few weeks, Ban ‘calls for swift and determined action against those claiming responsibility and perpetrating such actions,’ Nesirky said in a statement.

He ‘reiterates the strong support of the United Nations for efforts by the Government and people of Pakistan to protect religious and ethnic minorities and to combat the scourge of terrorism,’ the spokesman added.
