Several tankers transporting fuel to coalition troops in eastern Afghanistan caught fire after a mine placed in one of them exploded.
The blast in Jalalabad came on one of the heaviest days for casualties among the Nato-led international force ISAF, with five soldiers reported killed in two separate attacks.
On Saturday the Taliban attacked an airport and a military base in the east.
Up to ten militants were killed, according to police, the bodies of some found nearby.
Violence is at its worst since the Taliban’s overthrow nine years ago. An ISAF spokesman told euronews that in some cases, it is because coalition troops are actively seeking out the militants.
“The increased (amount) of violence and also the increased number of confrontations in certain areas, particularly in southern and eastern Afghanistan, is actually due to the fact that we have got in all the necessary reinforcements that allow us to confront the Taliban in their pockets and their strongholds, for example in the vicinity of Kandahar city,” said Brigadier General Josef Blotz.
Kandahar is one of the most dangerous areas. The NATO-led force has admitted an Afghan child was inadvertently killed by coalition troops. In the south a bomb at a market killed two civilians and wounded nine.
“Every single trip here in Kandahar has the tightest security”, said euronews correspondent Valérie Gauriat. She was speaking aboard a military convoy heading for the governor’s headquarters in Kandahar province, scene of frequent clashes between coalition forces and the Taliban. On the day euronews visited a Kandahar market, two policemen were killed.
Afghanistan will top the agenda when NATO leaders gather in Lisbon later this week – under increasing pressure to justify their continuing support for the drawn-out war.
