Violent Afghan protests spread over Koran burning

Hundreds of Afghans threw stones, shouted "death to America" and torched tyres, pouring onto streets on Wednesday for a second day of angry protests against NATO troops for burning copies of the Koran.

About 500 protesters threw stones at a US military base in Kabul, while in the eastern city of Jalalabad more than 1,000 demonstrators blocked the highway shouting "Death to Americans, Death to Obama", journalists said.

Afghanistan is a deeply religious country where slights against Islam have frequently provoked violent protests and Afghans were incensed that any Western troops could be so insensitive, 10 years after the 2001 US-led invasion.

In Kabul, the crowd attacked anti-riot police, forcing them to retreat, an AFP photographer said. At least one protester was shot, he said, without being able to identify where the shots came from.

Troops guarding the base, Camp Phoenix, fired in the air, he said, while black smoke from burning tyres rose above the demonstration in the Hod Khail neighbourhood.

A second protest erupted in west Kabul, involving about 100 university students, a police spokesman said, adding that riot police were present and the demonstration was under control.

The Jalalabad protest also involved university students, who chanted "We cannot tolerate insults to the sacred religion of Islam" as they prepared to burn an effigy of US President Barack Obama, an AFP reporter said.

The crowd blocked the key highway from the capital Kabul through the eastern provinces to the Pakistani trade port of Turkham.

On Tuesday, protests erupted in Kabul and outside the US-run Bagram military base, north of the capital, as word spread that NATO troops had burnt copies of the Koran.
