An
avalanche rescue operation was quickly launched by the Pakistani military. Over 150 soldiers—using helicopters,
rescue dogs, and heavy machinery airlifted from the main
garrison in
Rawalpindi—began searching the area for the missing soldiers and contractors, with "a team of doctors and paramedics" standing by. Local reports initially indicated that the operation had recovered at least 12 bodies by the end of the day, but official reports stated that no victims had been found, dead or alive. highlighted in maroon Due to the remoteness and extreme weather conditions, rescue operations were expected to take several days to complete. Nevertheless, official Pakistani military sources remained "hopeful", but despite initial hopes for clearer conditions, inclement weather continued to hamper the operation. A team of eight US military experts sent to Pakistan to assist the over 300 Pakistanis—286 soldiers and 60 civilians by this time The Pakistan Army had dispatched its chief of staff, General
Ashfaq Parvez Kayani, to the Siachen region to lead the operation. By 10 April, the rescue crew had increased to 452 people, 69 of them civilians, with nine pieces of
heavy machinery pressed into service for digging out the avalanche site, and had begun excavating five points on the disaster site in search of victims—two with heavy machinery, three without. The teams from Germany and Switzerland had arrived in Rawalpindi, joining the American team, which had still not yet reached the site due to weather. A seven-man specialist team was using life detection kits and thermal imaging cameras in an attempt to detect any residual body warmth from those buried under the snow and debris. The Pakistan Army released a revised list of those missing, the number climbing to 138. Snow was expected for the next two days, further frustrating rescue efforts as the possibility of finding survivors dwindled to next to none. As of 8 June 2013, search & rescue teams of the army had recovered 131 dead bodies while search for the remaining nine continued. On 2 October 2013, Pakistan Army Chief General Ashfaq Pervez Kayani said that 133 bodies had so far been recovered from Gayari sector while search for the remaining seven continued. ==Speculation about causes==
