At least 10 people were killed and 30 others were injured on Sunday in a bomb blast in Pakistan's Federally Administered Tribal Areas region.
The incident took place in Saddar market of Parachinar city, Daily Pakistan quoted a police official as saying.
The injured were shifted to a nearby hospital where as many as seven people were in serious condition, the official said.
The toll was expected to rise further, the aid workers said.
On Saturday, at least one soldier was killed and four others injured when a bomb exploded at a paramilitary checkpoint in southwest Pakistan.
The bomb was planted close to the Frontier Corps checkpoint and exploded just when soldiers reached the site in Quetta, in Baluchistan province, senior police official Abdul Waheed Khattak told AFP.
'It was an IED (improvised explosive device) which exploded the moment soldiers reached the checkpoint,' Khattak said.
'(The) condition of another soldier is also critical,' Khattak said.
Baloch rebels fighting for independence are pitted against thousands of Pakistani paramilitary troops in these areas. There has been a 10-year military operation against the Baloch insurgency.
No group has yet claimed responsibility for the latest attacks.
The blasts came even as Pakistan's military announced it had achieved 'phenomenal successes' in the war on terror by killing 3,400 'terrorists' since 2014, when it launched a major operation in a tribal region near Afghanistan.
Army spokesman Lt Gen Asim Saleem Bajwa said security forces are currently clearing out the 'last pockets' of insurgents in the former militant stronghold of North Waziristan.
He added that the army has lost 488 security personnel since June 2014 when it launched the operation., according to the Daily Mail.
