Germany has launched a poster campaign - 'Operation Last Chance II' - this week to find any remaining Nazis and bring them to justice.

The poster which depicts the entrance to the Nazi concentration camp, Auschwitz, says:

"Late, but not too late. Millions of innocents were murdered by Nazi war criminals. Some of the perpetrators are free and alive. Help us take them to court."

In a statement, the UNHRC says the policy lacks "adequate protection standards for asylum seekers".

The US has announced it will not deliver four F-16 fighter jets to Egypt, as political instability continues to bring unrest to the country.

"Given the current situation in Egypt we do not believe it is appropriate to move forward at this time with the delivery of F-16s," Pentagon spokesperson George Little told reporters.

"We remain committed to the US-Egypt defence relationship as it remains a foundation of our broader strategic partnership with Egypt and serves as a pillar of regional stability," he said.

The leader of Tunisia's opposition party, Mohamed Brahmi has been shot dead in Tunis, becoming the second politician to be assassinated this year.

Tunisian Prime Minister Ali Larayedh condemned the assassination while defying calls to step down and "dissolve the government to create a [power] vacuum."
