A roadside bomb killed three Canadian Nato soldiers in southern Afghanistan today.

British and Afghan forces attacked Taliban strongholds today after repelling a brazen insurgent attack on a police headquarters a day earlier in a southern Afghan town, killing at least 19 militants, the governor’s spokesman said.

Taliban militants crept up on an Afghan government office under cover of darkness early today and launched a gunbattle that left four attackers and three Afghan troops dead, police said.
