strike at Azam Warsak village in South Waziristan on July 28 that also reportedly killed al Qaeda explosives expert Abu Khabab al-Masri. Taliban Mehsud spokesman Maulvi Umar told the Associated Press on August 2, 2008, that the report of al-Zawahiri's injury was false. In early September 2008, Pakistan Army claimed that they "almost" captured al-Zawahiri after getting information that he and his wife were in the Mohmand Agency, in northwest Pakistan. After raiding the area, officials didn't find him. In two videos posted on Jihadist websites in 2012, al-Zawahiri called on Muslims to "capture" foreign citizens to leverage the release of Omar Abdel-Rahman, mastermind of the 1993 World Trade Center bombing. In the videos, al-Zawahiri cited to the successful kidnapping of Jewish American Warren Weinstein in 2011 as precedent for further kidnappings. Al-Zawahiri also called for the institution of Sharia law in Egypt and questioned the views of then-President of Egypt Mohamed Morsi. In June 2013, al-Zawahiri arbitrated against the merger of the Islamic State of Iraq with the Syrian-based Jabhat al-Nusra into Islamic State of Iraq and the Levant as was declared in April by Abu Bakr al-Baghdadi. Abu Mohammad al-Julani, leader of al-Nusra Front, affirmed the group's allegiance to al-Qaeda and al-Zawahiri. In September 2015, al-Zawahiri urged Islamic State (ISIL) to stop fighting al-Nusra Front, the official al-Qaeda affiliate in Syria, and to unite with all other jihadists against the supposed alliance between America, Russia, Europe, Shiites and Iran, and Bashar al-Assad's Alawite regime. Ayman al-Zawahiri released a statement supporting jihad in Xinjiang against Chinese, jihad in the Caucasus against the Russians and naming Somalia, Yemen, Syria, Iraq and Afghanistan as battlegrounds. al-Zawahiri endorsed "jihad to liberate every span of land of the Muslims that has been usurped and violated, from Kashgar to Andalusia, and from the Caucasus to Somalia and Central Africa". Uyghurs inhabit Kashgar, the city which was mentioned by al-Zawahiri. In another statement he said, "My mujahideen brothers in all places and of all groups ... we face aggression from America, Europe, and Russia ... so it's up to us to stand together as one from East Turkestan to Morocco". In 2015, the Turkistan Islamic Party (East Turkistan Islamic Movement) released an image showing Al Qaeda leaders Ayman al-Zawahiri and Osama Bin Laden meeting with Hasan Mahsum. The Uyghurs East Turkestan independence movement was endorsed in the serial "Islamic Spring"'s 9th release by Al-Zawahiri. Al-Zawahiri
