Kabul: Thousands of Afghan protesters are out on the streets in two eastern provinces in new rallies over the burning of Quran at a US military base in Afghanistan.

About 100 people also rallying in the capital Kabul on Friday.

Apologies by President Barack Obama and Afghan and US officials have failed so far to quiet the Afghan people's outrage over the incident. The US-led military coalition says the Quran and other Islamic texts were sent to a burn pit by mistake.

Afghan police in Khost, the provincial capital of Khost province, say an estimated 4,000 protesters are marching toward the governor's compound.

And in the eastern part of Nangarhar province, thousands are shouting "Death to America!" and burning a cardboard picture of Obama.
