'Semi-senior' terror chiefs caught in Pakistan offensive

US and Afghan troops have captured “semi-senior” terrorist leaders along the border with Pakistan, an Afghan government spokesman said in Kabul today.

The news came as border officials said Pakistan appeared to have blocked roads leading from the showdown in the South Waziristan tribal area, where Pakistani officials said forces had trapped al-Qaida Number 2 Ayman al-Zawahri in a massive four-day offensive.
