Pakistani commandos cornered a group of Taliban militants in an office building on a naval base in Karachi today after the insurgents raided the complex in an attack which destroyed two US-supplied surveillance aircraft, officials said.

A roadside bomb ripped through a bus taking Pakistani navy staff to work in Karachi today, killing three people in the third such attack in the country’s largest city this week.

About 60 people died today when their overloaded ferry capsized in the Arabian Sea off southern Pakistan, a navy spokesman said.
