A remote-controlled bomb blast in Kabul hit a bus carrying Afghan army personnel on Tuesday, killing at least four soldiers.

The Taliban claimed responsibility for the attack, which comes amid near-daily violence around Afghanistan as international security forces prepare to withdraw from the country by the end of the year.

The insurgent group opposes the foreign presence and Afghanistan's Western-backed government. It has stepped up its attacks against Afghan and NATO troops in recent months.
