At least four people were killed due to a landmine explosion in southeastern Khost province of Afghanistan on Sunday, media reports said. The blast is said to have taken place at a market. Sarhadi Zwak, a spokesman for the provincial governor, says two others were wounded in that attack.
No one claimed either attack, but the Taliban are active in both provinces.
As the holy Muslim month of Ramadan began on May 27, a Taliban auto bomber targeted an Afghan militia group in Khost, leaving 13 people dead.
A USA -led invasion drove the Taliban from power in Afghanistan after the September 11, 2001, terrorist attacks in the United States - carried out by Al-Qaeda, whose leaders were harbored by the Taliban in Afghanistan.
But the government is struggling to beat back insurgents in the wake of the exit of most North Atlantic Treaty Organisation forces in 2014.
Several terrorist related activities and explosions have been reported in the provincial capital and other parts of the province since the start of the year.
