Pakistan issued a strong condemnation after its ambassador to Sri Lanka narrowly survived a mine attack in Colombo on Monday.
"We strongly condemn it. We also regret the loss of precious lives," Foreign Ministry spokeswoman Tasnim Aslam said.
"The attack was on our high commissioner who is safe but his car is damaged. Three members of his security team were injured."
She added that Bashir Wali Mohamed had been returning from a flag-raising ceremony for Pakistan's Independence Day when he was attacked.
Pakistan is one of the Sri Lankan government's biggest arms suppliers.
