United Nations- United Nations chief Ban Ki Moon condemned the attack on Karachi’s old airport, in which 30 people were killed, and called on the government to address terrorism and religious extremism.

Mr Ban also condemned suicide attacks targeting Shia Muslims in Pakistan's south-western province of Baluchistan, which a local official told killed at least 24 pilgrims.

The UN secretary general strongly condemned the two attacks and said it is "deeply concerned by this upsurge of violence across Pakistan," his spokesman Stephane Dujarric said in a statement.

"While acknowledging the measures already taken to maintain security, he urges the government of Pakistan to further increase its efforts to address terrorism and religious extremism, including with a view to protecting the rights of all people to safely practice their religion, and to bring the perpetrators of such attacks to justice," the spokesman added.
