Muslim separatists hurled pipe bombs at an army checkpoint in Buddhist southern Thailand.

The suspected insurgents are believed to have carried out the attacks near the home of a military chief and special operations police base in the Panare district of Pattani province on June 28.

Footage shows how a thundering blast hit a road barrier before several more crackling explosions followed when the attackers reportedly opened fire.

There were no immediate reports of injuries or casualties.

Islamic separatist terror attacks target the three southernmost provinces of Thailand - Yala, Pattani and Narathiwat - next to the border with Mulsim neighbors Malaysia. Thai state employees and infrastructure are often hit while attacks on civilians are rare.

Officials believe the conflict dates to a deal in 1909 that the British Empire struck to incorporate the Muslim region into the Siamese mainland.

The region's culture is more similar to Malaysia and dramatically different to Buddhist Thais causing decades of tension that lead to the emergence of separatist groups fighting for independence in the 1960s.

The struggle has continued ever since with more than 7,344 people killed and 13,641 injured between January 2004 and March 2022.

The British Foreign & Commonwealth Office warns against all but essential travel to the region while Canada's government warns its nationals to 'avoid all travel' to the three provinces.
