Indian Prime Minister Narendra Modi on Saturday condemned the bomb attacks in Afghanistan's capital Kabul, which left at least 35 people dead.

"I strongly condemn the gruesome & cowardly attacks in Afghanistan. My thoughts are with families of the deceased & prayers with the injured," the Prime Minister's Office said in a tweet.

At least 35 people were killed and hundreds more injured in bomb attacks in Kabul on Friday and Saturday.

A suicide bomber blew himself up near the city's police academy on Friday evening, killing 20 recruits, while a truck bomb went off early Saturday in the largely residential Shah Shahid area, causing one of the largest explosions the city has ever experienced and leaving 15 dead.
