UN Secretary-General Ban Ki-moon Thursday strongly condemned the suicide bombings apparently targeting senior military figures in the Pakistani city of Quetta, which has killed scores of people and injured many others.

In a statement released by his spokesperson, Ban voiced deep sadness at "the continued loss of Pakistani lives at the hands of terrorism" and offered his condolences to the families of the victims and to the government of Pakistan.

"The Secretary-General commends the efforts of the Pakistani government to combat terrorism and wishes to re-confirm the solidarity of the United Nations with the people of Pakistan to that end," said the statement.

At least 25 people were killed and 55 more injured when Pakistan's southwestern city of Quetta were hit by twin bomb attacks on Wednesday morning, according to local reports.
