The bodies of David Miller, 24, and Hannah Witheridge, 23, were found on a beach on the southern Thai island of Koh Tao on September 15. Police arrested Myanmar workers Zaw Lin and Win Phyo,both 21, in October, saying DNA taken from the pair matched samples found on the victims.
On Thursday, Thai prosecutors filed charges against the Myanmar men ranging from conspiracy to commit murder and rape to illegal entry. They were taken to court on the island of Samuion Monday to hear the charges.
"They pleaded not guilty to all the charges today," Thanu Akekachote, a lawyer representing the pair, told Reuters.
