In a statement on Monday, Foreign Ministry Spokesman Abbas Mousavi condemned the Friday’s deadly attack on Filipino troops that has been claimed by the Daesh (ISIL) terrorist group.
The Iranian diplomat also expressed sympathy with the government and nation of the Philippines, particularly with the families of victims of the attack.
Three soldiers were killed and 12 wounded in two bomb explosions at the army camp in Indanan town in Sulu province, 1,000km south of Manila, on Friday.
The attack was carried out by two suicide bombers who were killed in the blast.
The camp was the headquarters of the army's 1st Brigade Combat Team, which was recently deployed to Sulu for war on the Abu Sayyaf terrorist group.
The Abu Sayyaf is believed to be allied with the Daesh terrorist group and has been blamed for some of the worst terrorist attacks in the Philippines.
