Kabul, May 6 (RHC)-- At least two people have been killed and four others wounded in a bomb explosion that destroyed their vehicle in Afghanistan's eastern province of Ghazni.

Provincial officials said the incident took place in the Deh Yak district of the province, located approximately 30 kilometers (18.5 miles) east of the provincial capital of Ghazni, on Wednesday morning, when the civilians' car ran over a buried explosive device. The victims were reportedly two children, and police said four men also sustained injuries in the attack.

No individual or group has claimed responsibility for the act of terror. However, such incidents are usually blamed on Taliban militants.

Roadside bombs and improvised explosive devices are by far the most lethal weapons Taliban militants use against Afghan forces, foreign troops, and civilians.

Latest official data show that around 30 bomb attacks were carried out in Afghanistan in April. Meanwhile, more than 200 people, a great proportion of them civilians, lost their lives and nearly 400 others sustained injuries in a spate of terrorist attacks during the same period.

Afghanistan faces a security challenge years after the United States and its allies invaded the country in 2001 as part of Washington's so-called war on terror. The offensive removed the Taliban from power, but some areas in the country are still witnessing violence, which threatens stability.
