Seven Afghan soldiers were killed in a Taliban attack on a base in northern Afghanistan on Tuesday, officials said, as local and international forces brace for another deadly winter.

According to the Afghan defence ministry, “terrorists” attacked a joint military base in the Dawlat Abad district of Balkh province near the Uzbekistan border.The base was shared between the army and the National Directorate of Security, Afghanistan’s secretive intelligence agency.

“As a result of this attack, seven Afghan army soldiers died and three others were wounded. Meanwhile, in this attack, three NDS staff were also injured,” the defence ministry said in a statement.

The attack comes one day after the Taliban claimed responsibility for the death of an American special forces soldier, who was killed in Kunduz province, also in the north.

The Taliban said they had attacked the vehicle he was in, whereas the US military said he died when a weapons cache he had been investigating exploded.

Winter once marked a slowdown in the so-called “fighting season”, with Taliban fighters returning to their villages while snow and ice made attacks more difficult to pull off.

According to German intelligence officials at Camp Marmal, a German-run base outside Mazar-i-sharif in Balkh, January 2019 saw one of the highest-ever numbers of attacks in the north.

In October, local officials said a column of hundreds of Taliban fighters on motorbikes attacked Shortepa district police headquarters in Balkh, briefly capturing the facility.
