FBI agents in the United States have agreed to help with forensic analysis after last week's crash of a Russian airliner in Egypt.

The British government suspects a bomb exploded on board, killing all 224 passengers and crew.

Egyptian crash investigators are complaining about the lack of intelligence sharing - and insist it is too early to say what caused the disaster.

Amid the confusion and uncertainty, thousands of tourists are still stranded in Sharm el-Sheikh trying to fly home.

So, who can we trust to tell the truth? And how much politics is involved?
