A soldier was killed and 11 were wounded on Monday when a bomb blast hit their truck in a tribal area near the Afghan border, an official said. The afternoon attack took place near Laddah fort, 40 kilometres (24 miles) north-east of South Waziristan's main town of Wana.
"One paramilitary soldier was killed and 11 were injured, nine of them seriously, when a remote-controlled bomb exploded near their moving truck," the official said.
Meanwhile, officials arrested an Afghan refugee on suspicion of planning to attack seminaries, in neighbouring North Waziristan district's main town of Miranshah, a tribal administration official told AFP.
"The military intelligence had intercepted his telephonic conversations from where they learned about his plans to bomb two local madrassas," he said.
