Afghan Taliban raided a base for foreign troops in Jalalabad on Wednesday, officials said, but there were no immediate reports of casualties. Local officials and those for the NATO-led International Security Assistance Force (ISAF) said the raid was still going on at the base in the northeast of the country near the Pakistan border. Since being overthrown in 2001, the Taliban have gone from strength to strength and are engaged daily in clashes with Afghan security forces and around 150,000 foreign troops.
