Thailand’s Prime Minister Paetongtarn Shinawatra apologized Thursday for the deepening political turbulence set off by a leaked recording of her negotiations with Cambodia’s former leader in the two nations’ latest border dispute.

BANGKOK (Reuters) -Thai Prime Minister Paetongtarn Shinawatra on Thursday apologised after a phone conversation between her and former Cambodian Prime Minster Hun Sen was leaked. Paetongtarn said the call was made from her personal phone and she did not know the conversation would be recorded and made public.
