(AP Photo/Rajanish Kakade) (Newser) – Four terrorists have entered India and are planning to attack Mumbai over the holidays, say authorities, who have issued a terror alert for the city. Police last night said they believe the four belong to Lashkar-e-Taiba, the group blamed for the November 2008 attacks. Today, police set up checkpoints along major roads in the city, put additional men on patrol duty at public places, and released computer photographs of the four suspects, reports the AP. "The four men are planning violent attacks that are going to cause destruction," said a police commissioner. "The four have recently arrived in Mumbai. We believe the threat is serious."
