Afghan Taliban's summer offensive begins with series of attacks in Afghanistan

The Taliban's annual summer offensive has begun with attacks in different parts of Afghanistan.

The group attacked the Kabul's international airport, the US airbase in Bagram and a courthouse in Jalalabad.

According to the BBC, the Taliban offensive began with attacks before dawn on Monday first on the huge Bagram airbase.

One rocket fell outside the base, and three others were launched, but did not cause any damage.

Two rockets were then launched at Kabul airport, but did not cause any casualties and the airport remains open.

Gunmen then moved into a complex of government buildings, including a court, in the eastern city of Jalalabad, after a suicide attacker blew open the gates.

There are also reports of attacks on Ghazni in the centre, and Helmand in the south-west of the country.

Taliban leaders said last week that the offensive, which will be the last before Nato combat troops withdraw from Afghanistan, would cleanse 'the filth of the infidels' from the country, the report added.
