"With the joint operation by US, UK and France. the Syrian regime received the message that its massacres wouldn't be left unanswered", Erdogan told his ruling Justice and Development Party supporters in a meeting on Saturday in Istanbul.
"The innocent Syrian people should have been defended long ago", he added, according to a report from the Reuters news agency.
The United States, Britain and France carried out a wave of pre-dawn strikes against the Assad regime Saturday in response to a suspected chemical weapons attack that killed dozens of civilians on April 7. The Turkish leader also emphasised the importance of de-escalating the tension in the region.
The U.S., United Kingdom and France jointly launched strikes targeting the Assad regime's alleged chemical weapons research center near Damascus, a chemical weapons warehouse and a command center linked to chemical weapons located west of Homs, U.S. Joint Chiefs of Staff Chairman Joseph Dunford said at a joint news conference with American Secretary of Defense James Mattis.
Turkish President Recep Tayyip Erdogan held telephone conversations with the presidents of Russian Federation and France Vladimir Putin and Emmanuel Macron, Turkish media reports. He stressed that the political solution is necessary to bring peace in the country.
In a statement, the Turkish foreign ministry said the US-led operation "has eased humanity's conscience in the face of" the suspected chemical attack. "Base Incirlik was not involved in the strike".
Turkey's stance on the airstrikes has been generally positive, but nearly all messages urged for a political solution, reshaping Syria's future without the regime involvement and global determination against the use of violence against civilians rather than conducting a single and limited action.
"The conscience of the worldwide community is in no doubt about that".
