Meanwhile, India said on Saturday that the coup authorities in Myanmar had asked them to return a number of defected police officers who had fled to it, to avoid implementing the orders of the ruling military council.
Maria Zawali - an official in the Indian Mizoram State Police - said that she had received a letter from her counterpart in Valam district in Myanmar, requesting the return of 8 policemen "in order to strengthen friendly relations between the two countries."
The number of police in Myanmar who defected and refused to implement the orders of the military council reached 100, days after a bloody crackdown on the anti-coup protesters.
The Southeast Asian country has been plunged into turmoil since the military overthrew and detained elected leader Aung San Sochi on February 1.
