Besides, there will be 'Red Alert' in the capital from November 10 and 'Orange Alert' from November 7.

Sources said members of the intelligence agencies yesterday launched their security rehearsal at Zia International Airport (ZIA) and on some VIP roads to be used by VVIPs.

They said members of the Rapid Action Battalion (Rab) and other agencies staged mock exercise at ZIA and on some important routes to be used by the VVIPs.

Meanwhile, the security charge at the ZIA will be given to the Special Security Forces (SSF).

Civil Aviation sources said during the summit, 'Orange Alert' will continue at the ZIA and 'Yellow Alert' will remain in force the day before the summit.

Other forces will be deployed at the key points to ensure security of the heads of the government and state of Saarc member countries under the news security measures.

"About 20-22 thousand policemen will be needed under the new security measures. At present, there are about 9-10 thousand police deployed in the capital ahead of Eid. Many of them were brought from outside the capital," said a source.

Moreover, the law-enforcement agencies have been directed to raid different hotels, guesthouses and slums in the city. Strong vigilance on highways, waterways and border areas will be maintained.

When contacted, the director general (DG) of Rab told the news agency that the elite force will be assigned to some specific duties so that criminals cannot create any problem.

He said Rab will carry out the government directives to ensure the foolproof security during the summit.

Meanwhile, police have started picking up beggars to keep the capital clean ahead of the Saarc summit.

DMP Commissioner Mizanur Rahman told the UNB yesterday that they ordered the duty police at city's different points to capture the beggars and put them at the vagrant center run by the Ministry of Social Welfare at Mirpur.

"If the number of beggars surpasses the capacity of the center, we'll arrange some other places for them," the commissioner said.
