French officials disclose that two suspected al-Qaeda militants have been arrested in separate incidents at Charles de Gaulle airport in Paris.

Investigators believe the first man Karim Mehdi, a Moroccan national, to have links with al-Qaeda militants based in Germany who planned the attacks on New York and Washington.

The second man, Christian Ganczarski of Germany, is suspected of being involved in the April 2002 bombing of a synagogue in Djerba, Tunisia, in which 21 people were killed.

Four German peacekeepers are killed and dozens of other people injured in an apparent suicide attack on a bus in the Afghan capital Kabul.

The attack is the deadliest assault on International Security Assistance Force (Isaf) troops since they arrived in the country to bolster the government of President Hamid Karzai after the fall of the Taleban.

German Defence Minister Peter Struck blames "al-Qaeda terrorists", and remnants of the ousted Taleban for the attack.
