US and South Korea to 'deter' N.Korean aggression: Obama

US President Barack Obama said Wednesday he will work with South Korea to deter aggression and hold North Korea accountable after it allegedly torpedoed a South Korean warship last month. In the days ahead, our governments will continue to consult closely, and I look forward to meeting with (South Korean) President Lee (Myung-Bak) this month in Toronto. Together, we will ensure our readiness and deter aggression, Obama said. We will work with allies and partners to hold North Korea accountable, including at the United Nations Security Council, making it clear that security and respect for North Korea will never come through aggression, but only by upholding its obligations.
