Islamist and right-wing parties in Pakistan view Valentine's Day as a vulgar Western import.
The order came on Monday, a day before the world celebrates love on 14 February.
Last Valentine's Day Pakistani President Mamnoon Hussain urged Pakistanis to refrain from celebrating, arguing that it "has no connection with our culture and it should be avoided". He ordered the respondents "to ensure that nothing about the celebration of Valentine's Day and its promotion is spread on the electronic and print media".
"The blast light night in Lahore has also scared off the people", Kalam added, echoing others that said public celebrations in the country are always risky in light of the security risks.
But some in the country have begun using it to advertise its products, leading conservatives to label Valentine's Day as a Western interloper that is not compatible with traditional Pakistani values. Protesters have decried Valentine's Day festivities, saying that it celebrates premarital sex and glamorizes physical attraction.
Pakistan's Electronic Media Regulatory Authority (PEMRA) will monitor social media platforms, as well as any sort of printed or electronic content in order to determine if someone is breaking this ban.
A day after Islamabad High Court's order, police have been directed to confiscate red flowers and balloons on Valentine's Day.
A joint operation conducted in several Malaysian states February 6-8 resulted in the arrests of 27 suspects believed to be involved in cross-border Internet love scam syndicates, the Singapore Police Force announced Monday.
The anti-Valentine's Day movement in Pakistan has been building for some time now. This may be seen as a negative holiday, but at the end of the day, to some people, Valentine's Day is a chance where they can display their love and appreciation for people in their lives.
