Karachi naval base siege brought to an end

Pakistani troops have ended a siege by militants who attacked a naval base in the city of Karachi.

The troops are now said to be "mopping up" after the raid, which has left 10 soldiers and at least three attackers dead.

Reports that hostages, including foreigners, were taken have been denied.

The Pakistan Taliban says the raid was to avenge Osama Bin Laden's killing by US special forces on 2 May.
