Thai Muslims in the province have begun the celebration early morning and then joining mass prayers at nearby mosques.
The Eid Al-Adha or the Sacrifice Celebration Day is celebrated about two months after Aidil Fitri, marking the end of the sacrificial period.
During the festival, muslim families would give meat to the poor so that they too can join in the festivities.
In Songkhla's Hat Yai, a special police force from the Provincial Police Region 9 was deployed to reinforce the joint operation of military, police and administrative staff to ensure the safety of the business district during the Muslim festival.
More tourists are expected to visit Hat Yai, particularly from Malaysia and Singapore, to celebrate Eid Al-Adha over the weekend.
