Pakistan denounced on Wednesday an attack by Houthi militants in Yemen on a vessel in the Red Sea in which three of its citizens were killed. Yemen's coastguard said Tuesday a strike by the Iran-backed militants on a vessel left six dead, including Pakistanis and an Indonesian citizen. There has been no official comment from the Houthis about the incident. "I have learnt with deep concern about the unfortunate incident," Pakistan Foreign Minister Ishaq Dar posted on X, confirming three Pakistanis had been killed and one wounded in the attack. "Pakistan strongly condemns the Houthi attack on a non-combatant commercial vessel," Dar added. "We are in contact with the relevant Saudi authorities, as well as the internationally recognized Government of Yemen, to ascertain further details of the incident and the circumstances surrounding it," Dar said. Pakistan's interior minister, Mohsin Naqvi, is currently in Iran to discuss regional security, Pakistan's foreign office said on Wednesday.
