UN Secretary-General Antonio Guterres on Saturday strongly condemned the terrorist attack in Pakistan targeting political rallies and candidates, his deputy spokesman said.

The United Nations stands in solidarity with and supports the efforts of the government of Pakistan in the fight against terrorism, said Farhan Haq, the deputy spokesman, in a statement.

A suicide bombing in Mastung in Pakistan's southwestern Balochistan province that targeted an election campaign event killed 128 people and injured many others. The blast was the deadliest terrorist attack in Pakistan this year.

Guterres extended his heartfelt condolences to the families of the victims and to the government and people of Pakistan, said the UN statement.
