Patna, Apr 5 (IANS): Independent MLC candidate Rais Khan's convoy was attacked by a group of unidentified assailants in Bihar's Siwan district.

The assailants used AK-47 assault rifles to carry out the attack and fired at least 70 to 80 rounds on Khan's convoy on Monday night. Khan was not in the SUV the assailants had targeted.
