At least 30 people have been killed in renewed fighting in the Kurram district of Pakistan's northwest Khyber Paktunkhwa province.
It's the latest round of violence there this week.
But the fighting between Shia and Sunni Muslim groups has lasted for months.
On Thursday 48 people were killed in an attack apparently targeting Shia Muslims travelling in a convoy.
The region bordering Afghanistan has a long history of sectarian violence.
Al Jazeera’s Kamal Hyder has the latest from Islamabad.
