The French Prime Minister Manuel Vallssays that some of those linked to the attacks last week in Paris which killed 129 people used the migration crisis in Europe to enter France unnoticed. He was speaking on French state television. These individuals took advantage of the refugee crisis of the chaos, perhaps, for some of them to slip into France. Others were in Belgium already, and others I must remind you were in France. Mr. Valls warned that passport free travel in the EU was threatened unless external border controls were improved. The French government says only after the Paris attacks was it informed that the alleged ringleader Abdel Hamid Abaaoud had passed through Greece on his return from Syria.

The US house of representatives has overwhelmingly passed a bill to toughen the screening of the Syria men and Iraqi refugees entering the United States. The proposed new restrictions would require the heads of three US agencies to approve every Iraqi and Syrian refugee entering the country. The White House says threaten to veto the new bill. The Secretary of State John Kerry said the plan changes were contrary to American values. Out of the entire total of refugees, who were let into our country since 2009, only 2% were male of a fighting age similar to those people who are picking up the battle in Syria. You know, it's inappropriate for American, of all countries in the world to panic and to somehow turn our backs on our fundamental values.

The United Nations has passed a resolution calling on countries including the US, Britain and South Africa to release records about a mysterious plane crash that killed the then UN Secretary of General Dag Hammarskjold in 1961. An independent inquiry earlier this year found new information suggesting that the plane might have been shotdown by another aircraft over what is now was Zambia.

And scientists have discovered the species of song bird performs a tap dance so fast that it can't be seen by the naked eye. Researchers from Japan and Germany slow down footages of the blue capped cordon-bleu songbirds during courtship. Here's our science reporter Jonathan Web. Now, they've discovered that tap dance is in the courtship repertoire of both male and female cordon-bleus. The next step for the researchers is to try and pick whether the birds mate is wooed by the sight, the sound or the vibrations of this fancy foot work. Such is the agility of the songbirds show stopping quick step that could only be fully appreciated in super slow motion.
