UN spokesman Stephane Dujarric says Ban condemned "in the strongest terms" the latest attack today on a bus carrying Shiite Muslims in southern Pakistan which killed at least 45 people.
The UN chief called on Pakistan's government "to take all necessary measures to bring to justice the perpetrators of this despicable act," Dujarric said.
Ban says Pakistan "must uphold its obligations and commitments towards protecting its citizens, including all minorities," according to the UN spokesman.
