NEW DELHI (Reuters) - An Indian court jailed 11 Hindus for life on Friday for the murder of dozens of Muslims during riots in Gujarat in 2002 that shook India at a time Prime Minister Narendra Modi was the state’s chief minister.

The court sentenced 12 other people to seven years in jail for arson and other charges during the disturbances, in which 69 Muslims were killed, while another defendant was handed a 10-year sentence, prosecutors said.

The massacre occurred during a series of religious riots that flared for two months in Gujarat and killed more than 1,000 people, most of them Muslims.

The court called the massacre the “darkest day” but rejected prosecutors’ demand to sentence the defendants to death, after ruling that the attack was not planned.

A Hindu mob scaled the boundary wall of a housing complex in Ahmedabad, Gujarat’s largest city, in February 2002 before torching the homes in which Muslim families were trapped.

Among the victims were children and women who were burned to death.

The riots, among the worst since India’s independence from Britain in 1947, have dogged Modi’s political career for years after he was accused of not doing enough to stop the violence.

Modi, a Hindu, denies any wrongdoing and in 2013 a panel appointed by the Supreme Court said there was insufficient evidence to prosecute him.

The violence also tainted Modi’s international reputation even as he rose in power at home, culminating in his 2014 general election victory. The United States revoked his visa in 2005 but allowed him to travel there again after his election victory.

“NOT SATISFIED”

Dozens of people have been convicted for their role in the Gujarat riots, including a local lawmaker from Modi’s Bharatiya Janata Party who was later freed on bail on medical grounds.

Zakia Jafri, whose husband Ehsan, a former Congress party legislator, died in the blaze at the housing complex, said the sentences on Friday were too lenient.

“I am not satisfied with this verdict. I have to start all over again. This is wrong,” she told media.

The trial began in 2009 and four of the defendants died during the lengthy proceedings.

Jafri, who is fighting what may be the last legal battle to pin blame on Modi, says she saw her husband making repeated desperate calls to police for help but none came.

He was dragged out of his home by sword-wielding men and within minutes was stripped and killed, according to Jafri.

“This was a massacre. So many people came together to do this, so what happened was clearly the result of a conspiracy. The 24 people should have been sentenced to life in prison. We will appeal,” S.M. Vohra, a lawyer for some of the victims, told Reuters.

The court had dropped charges of criminal conspiracy against the accused, and acquitted 36 other defendants earlier this month.

Hindu mobs charged through Gujarat’s streets in a wave of reprisal attacks after 60 Hindu pilgrims died in a train blaze in February 2002.

A court convicted 31 people years later of arson in connection with the train fire but other inquiries have said the fire was an accident.
