The trial of 49 suspects, including 19 police officers, on charges relating to the brutal mob killing of an Afghan woman has adjourned in Kabul.

All suspects in the trial - in its second day on Sunday - face charges related to the March 19 killing of a 27-year-old woman named Farkhunda.

One of them admitted to dragging her by the hair, as shown in mobile-phone footage captured by a bystander.

A prosecutor read charges against 10 of the defendants, including assault, murder and encouraging others to participate in the assault.

The police officers are charged with neglecting their duties and failing to prevent the attack.

Prosecutors have alleged that Farkhunda was beaten to death in a frenzied attack spurred by a bogus accusation that she had burned a copy of the Quran.

The killing shocked many Afghans, though some public and religious figures said it would have been justified if she in fact had damaged a copy of the Muslim holy book.

Mobile-phone video of the assault circulated widely on social media.

It showed Farkhunda, who like many Afghans went by only one name, being beaten, run over with a car and burned before her body was thrown into the Kabul River.

The incident caused nationwide outrage, as well as a civil society movement to limit the power of clerics, strengthen the rule of law and improve women's rights.

Safiullah Mojadedi, head of the Primary Court, called for senior officials, including the Kabul police chief and the interior ministry's chief criminal investigator, to attend Sunday's court session.

He also ordered the arrest of another police officer who allegedly freed a suspect.

At least two of the accused told the court they had confessed under physical duress.

Afghanistan's judicial system long has faced criticism for its inability to offer the majority of Afghans access to justice.

Women especially are sidelined, despite constitutional guarantees of equality and protection from violence, a recent report by the UN concluded.
