A crude bomb exploded outside a courtroom in eastern India on Friday, killing two people and wounding ten, television channels said, just days before Republic Day ceremonies that have been attacked in the past in troubled parts of the country. The blast occurred in Bhojpur district in the impoverished eastern state of Bihar, parts of which have been racked by a Maoist insurgency, CNN-IBN said. Both the dead were women, including a police constable. Several states in northern and eastern India are on heightened alert for the Republic Day celebrations on Jan. 26. The main parade will be held in the capital, New Delhi, which will be attended by U.S. President Barack Obama.
