Protests, marches and sit-ins are being planned across Papua New Guinea today to focus on the issue of increasing violence, especially against women.
The Haus Krai or House of Mourning is a response to the murders of several women, who had been accused of sorcery.
The deaths drew international condemnation and the government has promised action, including plans to start enforcing the death penalty.
Activities in Port Moresby centre on the resumption of parliament at Waigani, though police have confined events in the capital to the Sir John Guise stadium.
Our correspondent, Todagia Kelola, says activities there will start at 5pm and continue throught the night, before a petition is presented to the prime minister, Peter O'Neill.
"There will be music and prayer till dawn then eight o'clock on Wednesday there will be music and drama concert. At 11 there will be tribute songs and then the prime minister will arrive there at 1pm tomorrow where he will receive the petition from women leaders and the churches."
