Pakistani social media celeb Qandeel Baloch killed by brother. Twitter torn

Pakistan's social media celebrity Qandeel Baloch was killed allegedly by her brother in Multan in Punjab province, becoming the latest victim of "honour killings" that plague the country.

The 26-year-old actor-cum-model was killed in central district of Multan last night, police said today.

Police said she was killed by her brother named Wasim, who fled the spot soon after the incident.

"She was suffocated to death by strangulation. It seems to be a case of honour killing but we are investigating it," district police chief Azhar Akram said.

She had received threats from her family to quit modeling and her provocative appearances on social media. Her brother had been threatening her over her Facebook posts and videos, said the police.

Three weeks ago, she had written to the interior minister, the director general of the Federal Investigation Authority (FIA) and the senior superintendent of Islamabad, asking them to provide security to her, Dawn reported.

She had said her life is in danger and that she is being threatened via calls. Qandeel reportedly had no security apparatus installed at her home.

Qandeel - a media sensation and unbelievably bold - was also considered highly controversial. She shot to fame in Pakistan in 2014 after a video of her pouting for the camera went viral.

She became famous through her tireless self-promotion and suggestive "selfies" posted on social media and amassed tens of thousands of followers.
