Peshawar, Pakistan (Reuters) - Pakistan has indefinitely closed two border crossings with Afghanistan after opening them for two days to let through Afghans with visas, officials said on Thursday.

The official border crossings were abruptly ordered closed last month after a series of attacks Pakistan blames on militants sheltered in Afghanistan, heightening tension between the neighbours.
