ISLAMABAD (AP) - Pakistan's army says a Yemeni national it describes as a "senior al-Qaida operative" has been arrested in the city of Karachi.
The army said Tuesday the man had been working directly under al-Qaida leaders along the border between Pakistan and Afghanistan. It gave no further details. Pakistan has been under international pressure since the May 2 American raid on Osama bin Laden, who was living in a garrison town not far from Islamabad because of questions about whether Pakistan knew he was there or helped him hide. Pakistan has hotly denied both allegations.
Meanwhile, there are new strains today on Pakistan's relations with the United States. Local officials say a NATO helicopter crossed into Pakistani territory and opened fire on a border post today, wounding two soldiers. A Western military official in Afghanistan gave a different version of events.
