Pakistan's Interior Ministry has warned of fresh terror attacks by the Taliban in all major cities, including Lahore, Islamabad and Peshawar.

According to a notification issued by the ministry, a group of 15 trained militants from the restive Waziristan region could wreak havoc across the country in coming few days.

Army helicopters and aircrafts could also be targeted by militants there are reports that they also possess a 12.7 mm anti-aircraft gun, The Daily Times reports on Thursday.

Terror activities in Pakistan has increased substantially in Pakistan in the past few days with extremists striking at their will killing dozens of people in various parts of the country.

Last week, Lahore was rocked by two powerful bomb blasts, killing more than 50 persons and wounding over 100 others.

A series of 14 low intensity explosions which followed the twin blasts triggered panic among local residents, who feared more blood shed.

The explosions came less than a week after a suicide car bomber tore through the office of the Special Intelligence Agency (SIA) killing at least 13 people and injuring over 20 others.

Following the recovery of a huge cache of arms and explosives from different part of Lahore, security agencies are planning a massive operation to bust 'militant hubs' situated in the outskirts of the provincial capital.

According to sources, law enforcement agencies are charting out a comprehensive plan targeting extremists hideouts in and around Lahore instead of conducting individual raids.

Police officials said they have received information regarding two high profile militants trying to enter Lahore using these militant hubs.

They also admitted that bringing weapons and explosives into these areas and then transferring them to the main town was very easy since militants hid in these 'friendly' locations and enter the city when officials at checkposts change their shifts.

Moreover, a majority of residents of these areas have transportation related jobs, which makes the work of transferring explosives and arms even easier.

"The region surrounding Lahore could be the main hub for importing weapons and ammunition into the city, as more over thousand trucks continuously travel across the country from the area," The Daily Times quoted an official, as saying.
