Pakistan's insurgent group Balochistan has reportedly claimed responsibility for the attack in the Clifton area of the city. Imran Khan has called the attack a "conspiracy" against China-Pakistan strategic ties.

According to local media reports, citing local eyewitnesses and police, a blast and several shots were heard near the Chinese diplomatic mission in the Pakistani city of Karachi.

From three to four men tried to enter the consulate and opened fire on the guard standing outside the building. The security guards, however, have managed to foil the attack, Dunyanews reported.

As seen in footages on social media, a thick plume of smoke has been emerging from the mission's premises following a loud blast.
