Pakistan on Monday tightened its security for the fifth anniversary of the September 11 attacks, using bomb-sniffing dogs to sweep parks in the capital and taking extra precautions at airports and army posts, a news report said.
Intelligence agencies have reported that militants or activists would try to "exploit the situation" by stepping up their "nefarious designs," The Daily Times newspaper said, citing unidentified officials.
No details were given. Interior Ministry public affairs officials could not immediately be reached for comment on the report.
Police will tightly enforce a law against unauthorised public gatherings in the capital, Islamabad, the report said, quoting various authorities.
Sniffer dogs were checking parks and other public places for explosives, it said.
Security was ramped up at army posts, Parliament house, foreign diplomatic missions and diplomats' homes in the capital, the newspaper said.
It said police were also closely watching train and bus stations to prevent attempted terrorist attacks.
