The Taliban unleashed a wave of attacks across Afghanistan on Tuesday, targeting police compounds and government facilities with suicide bombers in the country’s south, east and west, and killing at least 74 people, officials said.

Among those killed in one of the attacks was a provincial police chief. Scores were also wounded, both policemen and civilians, reports The Independent.

Afghanistan’s deputy interior minister, Murad Ali Murad, called the onslaught the ‘biggest terrorist attack this year.’

Murad told a press conference in Kabul that attacks in Ghazni and Paktia provinces killed 71 people.

In southern Paktia province, 41 people — 21 policemen and 20 civilians — were killed when the Taliban targeted a police compound in the provincial capital of Gardez with two suicide car bombs. Among the wounded were 48 policemen and 110 civilians.

The provincial police chief, Toryalai Abdyani, was killed in the Paktia attack, Murad said.

The Interior Ministry said in a statement earlier Tuesday that after the two cars blew up in Gardez, five attackers with suicide belts tried to storm the compound but were killed by Afghan security forces.

Health Ministry spokesman Waheed Majroo said the Gardez city hospital reported receiving at least 130 wounded in the attack.

Hamza Aqmhal, a student at the Paktia University, told The Associated Press that he heard a very powerful blast that shattered glass and broke all the windows at the building he was in. The university is about 2 kilometres (1.25 miles) from the training academy, said Aqmhal, who was slightly injured by the glass.
