The Tehreek-e-Taliban Pakistan, or TTP, have claimed responsibility for the attack that claimed at least 28 lives at Jinnah International Airport in Karachi, Pakistan, as an act of revenge against Pakistan's government for the death of Hakimullah Mehsud in a drone attack in November.
The TTP is an Islamist group, which was formed in 2007 as an alloy of various militant groups in the region, and was banned by Pakistan's government in 2008. The outfit is reported to be closely linked to al-Qaida and the Afghan Taliban with one crucial differentiating factor in that the TTP targets the Pakistani state while the Afghan Taliban does not.
Here is a look at 10 other attacks over the years that have been linked to the TTP:
10. TTP claimed responsibility for the attack on Malala Yousafzai, a teenaged Pakistani girl who actively campaigned for women's right to education, in Mingora, the largest city in Swat District in the Khyber-Pakhtunkhwa province of Pakistan, in October 2012. Yousafzai was shot in the head and neck while returning home from school, and the attack on her led to a massive show of support from the international community for the now-16-year-old, and widespread condemnation of the TTP, which seeks to ban girls from attending schools.
09. The TTP have been linked to a July 2012 attack on an army camp in Gujrat, a city in the Punjab province of Pakistan, which reportedly killed seven soldiers and a police official. The attack reportedly was in retaliation against the Pakistani government's decision to allow NATO to use its territory for transporting supplies to Afghanistan. A pamphlet, reportedly found by the police after the incident, claimed that the attacks would continue if NATO supply routes were not closed.
08. The Pakistani Taliban murdered 15 Frontier Constabulary personnel, who were abducted by the TTP in December 2010 when several militants attacked the Mullazai Fort in the Tank district of Khyber-Pakhtunkhwa bordering South Waziristan. The announcement of their killing was reportedly made in January 2012 and according to reports, each of the bodies, which were recovered from North Waziristan, had 40 bullet holes and showed signs of torture.
07. In May 2011, the TTP attacked a naval air force base in Karachi, Pakistan, killing at least 16 people, which included 10 soldiers.
06. The TTP targeted two Pakistani Navy buses in Karachi in April 2011, killing five people, included four navy personnel.
05. In April 2011, two suicide bombers attacked a Sufi shrine in Dera Ghazi Khan in central Pakistan, killing at least 41 people and injuring more than 70.
04. The Pakistani Taliban were held responsible for a car bomb explosion on March 2011 at a gas station in Faisalabad, a major industrial center in Pakistan, which killed at least 32 people and injured more than 125.
03. Two explosions, as part of a double suicide attack, at a government office in northwest Pakistan in December 2010 killed about 50 people, which reportedly included Haji Kachkol Khan, a senior leader of the local peace committee.
02. The TTP has been linked to a 2010 car bombing attack attempt in New York's Times Square.
01. The Pakistani Taliban claimed responsibility for a suicide bombing at the U.N food agency’s headquarters in Islamabad, killing five workers of the World Food Program in October 2009. The attack led to the temporary shutdown of its offices in the country.
