Thousands of Pashtun tribal people who for decades ignored the invisible line that bisects their dusty villages and demarcates the Afghanistan-Pakistan frontier are bracing for a Berlin Wall-style divide of their neighbourhoods. Pakistan, worried by Islamist attacks, is building a fence to prevent militants criss-crossing the porous 2,500km (1,500 mile) frontier along the disputed colonial-era Durand line drawn up by the British in 1893.
The fence, which Kabul opposes, will run down the middle of so-called "divided villages" where few people have passports and Pashtun tribal loyalty often trumps allegiance to the state.
