The Taliban have carried out two suicide auto bombings at an army base in Afghanistan's southern Kandahar province, setting of several hours of fighting and killing at least 43 soldiers, the defense ministry and an Afghan official said Thursday.
The Taliban claimed responsibility for the assault, the third major attack on Afghan security forces this week.
At least 55 Afghan soldiers have been killed in Taliban attacks in the provinces of Kandahar, Balkh and Farah in the past 24 hours.
Militants launched two separate attacks on Afghan security installations killing dozens of soldiers Thursday, the latest in a series of devastating assaults this week that left more than 120 people dead and underscored spiralling insecurity.
More than 120 people, including soldiers, police and civilians, have died in three such attacks this week.
United States and Japanese Officials Arrive in Seoul for Talks on N.Korea
Both sides flexing military muscle at a time of growing tensions over North Korea's nuclear and missile programme. The United States is not ruling out the eventual possibility of direct talks with North Korea.
The Taliban have been waging an insurgency for a decade and a half in an attempt to overthrow the government in Kabul.
And the base itself sustained major damage.
Beleaguered Afghan security forces have faced soaring casualties in their attempts to hold back the insurgents since North Atlantic Treaty Organisation combat forces pulled out of the country at the end of 2014.
In recent months, the Taliban have been attacking Afghan security forces on a weekly and sometimes daily basis.
It also said it was behind the suicide attack on a hospital in Quetta that killed at least 74 people.
Defence ministry spokesman Dawlat Waziri told AFP news agency the assailants detonated at least one explosive-packed truck and razed the compound. He also said that 10 attackers were killed.
