In Islamabad, Pakistan, a military operation is under way at the compound of the besieged Red Mosque, which has been controlled by hundreds of Islamist militants for a week. Talks for a peaceful resolution broke down early Tuesday local time, and sounds of gunfire were heard soon after.
The Islamist militant are supporters of hard-line clerics who have tried to impose a Taliban-style rule in Islamabad. There have been skirmishes between the militants and government forces since the siege at the mosque began, killing more than 20 people.
