"There is a need for truth and there is a need for justice, and these crimes have to be investigated and simply saying that we told lies or our evidence is faked, when it is not, it's not the way to do it. They cannot hide behind denouncing us...they cannot..."

"Free speech does not seem to be allowed in this country."
12. SOUNDBITE: (English) Jonathan Miller, British journalist:
"We listened to what the protesters said there. We understand that everybody in this country has got the right to express themselves. They did and they did it effectively. What they've done though they've stopped us listening to other peoples' voices further up the track. That's a real shame. We now have to go back to Colombo because we had to let those passengers, on the train, the other passengers go."

14. SOUNDBITE: (English) William Hague, British Foreign Secretary:
"I was disturbed to hear about the incident that took place early today affecting Channel 4. I think the, I think freedom of access for the media is very, very important and the absence of that would reflect very poorly on any country. And again any country that hosts a major International meeting of course will receive a great deal of media attention. And we believe in the Commonwealth, in the freedom of the media and freedom of speech."
Protesters lying on railroad tracks blocked a train carrying a UK TV crew on Wednesday, as they attempted to make their way to Sri Lanka's former war zone in the north.
Channel 4's Callum Macrae, along with a team from the UK news programme Channel 4 News, were in Sri Lanka to cover the upcoming Commonwealth meeting.
They were blocked in the north-central city of Anuradhapura, and the train to the northern town of Vavuniya was unable to move for more than three hours.
The team eventually abandoned their train journey to allow other passengers to move on.
Macrae made a documentary showing soldiers executing naked Tamils and other gruesome footage from the 138-day final offensive in the country's 27-year civil war.
Sri Lanka dismissed the video as fake footage and false journalism.
However British Prime Minister David Cameron said at the weekend that Sri Lanka had "serious questions" to answer after watching the documentary.
Speaking in the Sri Lankan capital Colombo on Wednesday, British Foreign Secretary William Hague said he was "disturbed by the incident " that had taken place involving the British team of journalists.
He stated that, to him, "freedom of access to the media is very, very important."
Sri Lanka will host a Commonwealth summit this weekend with the global focus trained on the country's 27-year civil war and alleged atrocities committed by both rebels and soldiers who, despite a sustained international outcry, have been spared from investigations and prosecutions since the war ended in 2009.
The leaders of Canada and India are boycotting the summit for those reasons.
Others have had to justify their plans to attend by promising to bring Sri Lanka's government to task.
Queen Elizabeth II, who is 87, is not going, but her son, Prince Charles, is presiding over the meeting.
Sri Lanka denies any rights abuses were committed by its forces and it has balked at demands for an independent investigation.
The country's leaders also accuse journalists of fabricating allegations of atrocities, and stand staunchly by a clan-like government that has alarmed many democracies in the West.
