United States Attorney General Jeff Sessions testified Tuesday before the Senate Intelligence Committee.

The hearing focused on the Russia investigation into the 2016 presidential election and the firing of then FBI Director James Comey.

Sessions began his testimony by stating that he had no contact with anyone allegedly trying to interfere with the election.

"I have never met with or had any conversations with any Russians or any foreign officials concerning any type of interference with any campaign or election in the United States."

He called the notion that he maybe have been involved in such activities an "appalling and detestable lie."

Sessions said he has no knowledge of the criminal investigation being headed by Robert Mueller, the special counsel, who assumed oversight of the Russia probe after Sessions recused himself.

Sessions said he has confidence in Mueller but added that he has no idea whether President Trump does.

Earlier in the day, Deputy Attorney General Rod Rosenstein assured lawmakers that without good cause, he would ignore any attempt by President Donald Trump to fire the special counsel investigating possible illegal collusion between Trump's aides and Russian officials.

"It doesn't matter who the order comes from, good cause would be based on the reasons for the proposed removal."

Rosenstein added that no such a reason currently exists.

An eight-story building has collapsed in a low-income area of Nairobi, Kenya.

A baby girl, a 10-year-old boy and their mother have been pulled from the rubble.

Two people are thought to be remaining inside the debris and one man is believed to be missing.

The collapse came months after the government ordered to demolish all condemned buildings in the area and evacuate their residents.

A court in Germany has convicted six Syrian and Libyan refugees in connection with an attack last Christmas on a homeless man who had been sleeping on a bench in a Berlin train station. Philip Alexiou has more.

Surveillance video of the incident shows the victim, a 37-year old Polish man, sleeping on a bench under a layer of paper sheets he had been using to keep warm. The main defendant can then be seen setting the paper on fire before the group of laughing young men runs away.

A train conductor and a group of [passer-bys] passers-by quickly put out the fire before the man was seriously hurt.

None of the youths attempted to help the man.

All six defendants entered Germany as asylum seekers in 2014 and 2016.
