A Taliban rocket attack on a NATO base in the eastern Afghan province of Kunar killed two international soldiers and wounded six, officials said. It came a day after gunmen dressed in Afghan police uniforms and wearing suicide vests stormed a government compound in the southwestern province of Farah, killing seven people and wounding 12 others. The Taliban this month announced the start of their annual spring offensive, a campaign of bombings and attacks that picks up every year as the weather warms.
