On 20 February 2009, two LTTE planes on a suicide mission carried out a kamikaze style air attack on the Sri Lankan capital Colombo, killing 2 and wounding 45, but both planes were shot down by the Sri Lankan Air Force before they could damage the intended targets which were the Army Headquarters and the main Air Force base. By late March, the Tamil Tigers controlled only one square kilometre outside the no-fire zone, down from about 15,000 km2 a mere three years earlier. Political pressure was placed on President Rajapaksa to find a political solution to the conflict and he called for a meeting with Tamil National Alliance, but they refused until the government resolved the humanitarian crisis faced by civilians trapped in the fighting.
