The Taliban says it has begun its spring offensive in Afghanistan with multiple co-ordinated attacks on several high-profile western targets.
Gunmen have attacked the British, German and US embassies and targeted the headquarters of the NATO-led military force in the capital Kabul.
Several Afghan MPs joined security forces in repelling attackers from a roof near the parliament building.
Insurgents fired rocket-propelled grenades at a house used by British diplomats.
US embassy officials say their building has been locked down while the attacks continue, though no staff members have been injured.
Afghan security forces scrambled to reinforce areas around the so-called green diplomatic section in the city centre.
The assaults are among the boldest carried out on the capital since the US-led force ousted the Taliban in 2001.
Elsewhere, two suicide bombers detonated their devices at Jalalabad airport – an important NATO base – wounding several people.
