Pakistan reacts angrily to tone of U.S. questions

The United States is pressing Pakistani authorities for answers about how Osama bin Laden could have lived close to a major military base near Pakistan's capital without the government knowing, two senior U.S. officials said Wednesday.

The al Qaeda leader was living in a walled compound in Abbottabad, about 50 km (31 miles) north of Islamabad, when he was gunned down by American commandos in a pre-dawn raid Monday. The killing has left Pakistani officials facing sharp questions from Washington - and in some cases, from their own people - and exacerbated an already rocky relationship between the two nations.
