Story highlights Australian and Philippines governments given notice their nationals will be executed in 72 hours

They include Philippines maid Mary Jane Velos and Australians Andrew Chan and Myuran Sukumaran

Australia has repeatedly appealed for clemency for the pair

(CNN) Nine of ten mostly foreign prisoners on death row in Indonesia have been given 72 hours notice ahead of their execution, according to a spokesperson for the Attorney General's office.

"Seventy-two hours notification means three days, at least, to go to the execution. It may be longer. In other words, there will be no execution less than 72 hours after notification," Tony Spontana told CNN by phone Sunday.

Though Indonesian officials said all 10 would be executed at the same time, Spontana said French national Serge Atlaoui had filed a challenge to the State Administrative Court on Thursday so his sentence has been delayed.

Meanwhile, Edre Olalia, a lawyer acting for Philippines maid Mary Jane Veloso, told CNN Sunday that Veloso had telephoned her sister on Saturday at about 5:30 p.m. local time and said her execution will take place on Tuesday, April 28. Officials at the Philippines Embassy in Jakarta confirmed the same information.

According to her lawyers, Veloso unknowingly carried drugs into Indonesia, and that she was set up by members of a drug syndicate.
