The government deployed military troops and police to fight the forest fires that cause regional air pollution and often are set illegally to clear land for farming. Police were investigating at least 130 cases of land and forest burning in several provinces, and President Joko "Jokowi" Widodo said those responsible could lose their forest concessions. Malaysia and Singapore have recorded poor air quality as the acrid, white haze drifts over Indonesia's neighbors. Schools have been closed, and Malaysia sent aircraft on cloud-seeding flights to try to induce rain to help clear the haze.
