LAHORE, Pakistan, March 13 (UPI) -- Pakistani police reportedly have no suspects in Tuesday's explosions that killed 24 people in Lahore, the country's second largest city.
Adding to authorities' concerns are reports that about half a dozen likely suicide bombers have arrived in Lahore, Dawn newspaper reported Thursday. Police have given no details about those reports.
The Tuesday attacks targeted the city's Federal Investigation Agency headquarters, where most of the deaths occurred, and a building in Lahore's Model Town where at least four of the 24 victims died.
Dawn said security has been tightened around the city's government and other large buildings.
"We have still found no clue to Tuesday's devastating suicide bombings and no arrests have been made," police official Tussadaq Husain told Dawn.
A similar attack March 4 on Lahore's Navy War College killed at least at seven people. Police arrested three suspects in that blast.
Husain told Dawn those suspects were being questioned about Tuesday's blasts.
The report said police have the chassis numbers of the two vehicles used in the bombings and have sent the limbs of the suspected suicide bombers for DNA tests.
