The Taliban has killed five people and injured 12 others in two attacks staged on the first day of its newly launched 'spring offensive', Afghan officials said.

A suicide bomber detonated his explosive-packed vest at a bazaar in the Barmal district of Paktika province, which is on the Afghan-Pakstani border, the interior ministry said in a statement on Sunday.

Three civilians were killed and 11 others were injured, and the provincial police have launched an investigation, the statement said.

In another incident, a gunman opened fire on a checkpoint in the southwestern province of Ghazni, killing two policemen and wounding a bystander during an hour-long battle, provincial police chief Zerawar Zahid said.

On Saturday the Taliban declared a new series of high-profile attacks against foreign troops and Afghan officials and military.

In a statement, the group warned citizens to stay away from public locations to prevent getting harmed during the offensive.
