LUCKNOW, March 3: A school boy and two persons were killed and 18 persons were wounded in trouble-torn Nazirabad and Aminabad areas of the Uttar Pradesh capital in communal violence, which erupted during an anti-Bush procession on Friday afternoon.
 
The Rapid Action Force and PAC have been deployed in all sensitive points in Lucknow.
  
The authorities curfew in Aminabad and Maulviganj but the shortage of police and presence of mobs on streets prevented them from enforcing the orders, an official said.
  
Police fired several rounds to disperse the mob, which indulged in stone-pelting, arson and looting. The Bank of Baroda building in Aminabad was set ablaze.
  
Shanu (12) -- son of Rajendra Kumar -- was shot dead in violence, which saw pitched battles between Hindus and Muslims.
 
The kin of the deceased had put his body on the road demanding the arrest of the person who pulled the trigger.
 
The report of another casualty from Maulviganj was not officially confirmed.
  
Trouble erupted immediately after the Friday prayers when an anti-Bush procession of Muslims was allegedly stoned in Nazirabad.
  
The problem started when members of a community were forcibly trying to close down shops in the busy market area from where the procession was passing, state Director General of Police Yashpal Singh said.
  
Trouble soon spread to others areas under three police stations of Kaiserbagh, Aminabad and Wazirganj.

 
With most of the police force being deployed for security in view of President A P J Abdul Kalam's visit later in the day, the situation turned worse within minutes, leaving the handful of policemen with no option but to open fire to control the mob.
  
The incident took the administration by surprise as it was busy making security arrangements for Kalam.
  
The situation was officially described as ''very tense.''

Police rejected charges the man was killed in the firing.
 
“Some of the rioters were carrying guns,” the police said.  
 
“We are deploying more people. We are also issuing warnings on public address systems to people to remain indoors and not indulge in violence or not get provoked,” they said.

Many Indian cities have been hit by anti-Bush protests this week. The U.S. president began a three-day visit to the country on Wednesday and Communist and Islamist groups have demonstrated against American actions, including the war in Iraq.
