国际英语新闻:Riot, Looting Prompt State of Emergency, Curfew in Baltimore

"It's a corrosion on justice," said Murphy in remarks at the funeral. "And we're calling for the police, the six of them that are at least being partially, if not totally, implicated to come forward and to tell it all just like you tell our citizens to do."

Gray suffered severe spinal cord injuries following his arrest on April 12. Officials said Gray was not restrained properly while being transported in a police van.

Protesters have been demanding justice in daily demonstrations that have been largely peaceful, but some incidents of vandalism and violence were reported in a march on Saturday.

The Baltimore Police Department had reported a "credible threat" that some violent street gangs were planning to target police officers.  Police have not clarified whether the threat was connected to the ongoing demonstrations.

Speaking on CBS television Sunday, Congressman Cummings said the relationship between police and communities is the civil rights cause for this generation.  He added that it is still not exactly clear why Gray was arrested and the entire situation is "very upsetting."

More information on the case is expected May 1, according to the Baltimore Police Department.

The agency placed six officers who had contact with Gray on paid administrative leave. The U.S. Department of Justice is investigating whether civil rights violations occurred.

Police-Community Relations

A string of deadly confrontations between mostly white police and black men, and the violence it has prompted, will be among the challenges facing U.S. Attorney General Loretta Lynch, who was sworn in on Monday.

Following her swearing in, Lynch signaled that improving relations between police and the communities they protect will be high on her agenda.

"We can restore trust and faith both in our laws and in those of us who enforce them," she said.

President Barack Obama pledged the federal government's help to respond to the Baltimore riots. Lynch met with the president in the Oval Office Monday evening as violent scenes of rioting played out on television.

Lynch condemned the violence that erupted in Baltimore on Monday and said the Justice Department would provide any assistance needed.

"I condemn the senseless acts of violence by some individuals in Baltimore that have resulted in harm to law enforcement officers, destruction of property and a shattering of the peace in the city of Baltimore," she said.

She added in her statement: "I will bring the full resources of the Department of Justice to bear in protecting those under threat, investigating wrongdoing, and securing an end to violence."
