In a statement issued on Monday, the Foreign Office said the attack appeared to be an attempt to undermine regional peace and stability.

“Such attacks constitute a serious violation of the Kingdom’s sovereignty and territorial integrity, and appear to be an attempt to further undermine the regional peace and stability,” the statement said.

The Foreign Office said the government and people of Pakistan stood in solidarity with the government and people of Saudi Arabia during this critical time.

Pakistan also reaffirmed its “full and unwavering support” for the kingdom’s security, peace and prosperity.

The statement reiterated Pakistan’s longstanding support for Saudi Arabia and underscored concerns over growing security challenges in the region.

Late Sunday, Saudi Arabia said it had intercepted and destroyed three drones that entered from Iraqi airspace, adding that it “reserves the right to respond at the appropriate time and place.”

Iraq’s foreign ministry said on Monday that the country’s air defence systems had not detected any drones launched from its territory toward Saudi Arabia.

The Iraqi foreign ministry said authorities had opened an investigation “to determine the circumstances surrounding the incident”.

The ministry urged Riyadh “to cooperate and share relevant information to help ensure accurate information that strengthens security and stability in both brotherly countries.”

No Iraqi group has claimed responsibility for the drones.
