In a small room on the edge of Tulkarm, they are wailing for 44-year-old Eitas Zalat.
Israel says Eitas Zalat was shot by mistake in an arrest operation
There are tears, screams, and whimpers. Women turn to me in sorrow, and in anger.
Eitas Zalat was a mother of five. She was killed at dawn by an Israeli army bullet while sitting in her living room.
Now she lies on a stretcher on the floor. Women kiss her face, and then collapse.
Outside one of Tulkarm's mosques, as the people of this impoverished West Bank town prayed, I spoke to Eitas Zalat's husband.
Yousef Zalat is an English teacher. He is still - I think, as we speak - in shock.
"I feel just like an ordinary man who lost his partner," he tells me.
"We were sitting next to each other and the Jews shot her while we were speaking together. There were no weapons, there were no bombs. Why they do this? Why?"
In a place as complex as the Middle East there are many answers to that question. Two are worth noting here, I think.
The first is the Israeli army's answer. I called the spokesperson's unit and was told Israeli soldiers had gone to Tulkarm to arrest a leader of the Palestinian militant group Islamic Jihad.
Such arrests are an almost nightly occurrence across the West Bank.
The Israeli army said they surrounded a building they believed he was in. They called for people to leave the apartment building. No one did.
Then - the army says - soldiers saw a "suspicious movement" at a window. They thought they would be fired at, so the soldiers opened fire at the house.
Mrs Zalat was killed. The army says it made a mistake. It has apologised.
That is one possible answer to Yousef Zalat's question, "Why?"
'Pattern of indifference'
Another comes from an Israeli human rights group, B'Tselem.
The circumstances under which Eitas Zalat was killed, the group says, "raise the grave suspicion that Israeli security forces acted as if they were conducting an assassination rather than an arrest operation".
Eitas Zalat was buried 12 hours after being shot dead
B'Tselem says that between January 2004 and 1 May 2006, 157 Palestinians were killed in what Israeli forces term arrest operations in the West Bank.
Of these, at least 35 were civilians, whom the military admits were mere bystanders to the operation.
B'Tselem accuses the Israeli army of "demonstrating a pattern of indifference to the safety of Palestinian civilians".
Such words though do not comfort Palestinians.
The death of Mrs Zalat is for them just another illustration of how deadly Israel's occupation of their land often is.
It shows - they say - how they are the victims of this conflict.
Mr Zalat told me one of the soldiers had apologised to him. "What good it that?" he asked. "My wife has been killed."
Then, Mrs Zalat's body was carried on a stretcher to the cemetery.
A few hundred mourners picked their way among the gravestones in the spring sunshine.
And there they stood, as speeches were made, and as the body was lowered into the ground.
Mr Zalat crouched by the grave, and took one last look at his wife. He stroked his face. It was just 12 hours since she had been killed.
Another death that changes nothing in this conflict, but changes everything in one family.
