ISIS kills dozens in Pakistan shrine bombing

A suicide attack in a popular shrine in southern Pakistan has killed at least 72 people, police say.

The bomber blew himself up among devotees in the shrine of Sufi saint Lal Shahbaz Qalandar in the town of Sehwan, in Sindh province, police said.

Prime Minister Nawaz Sharif has condemned the attack, which has been claimed by so-called Islamic State.

A surge of attacks this week has shattered a period of improving security in Pakistan.

The shrine was crowded as Thursday is considered a sacred day for Muslims to pray there.
