Bangkok ( CNN ) -- It 's a life experience nobody would want to endure -- attending your child 's funeral . But that 's what some parents have had to do in Thailand in recent days , as the country 's anti-government unrest has taken an increasingly ugly , more violent turn with children killed or injured , their tiny bodies maimed and turned lifeless by shrapnel or gunshots . A six-year-old-girl , a four-year-old boy and a woman of about 40 died when a grenade detonated at an anti-government rally outside a shopping mall in the Ratchaprasong area of Bangkok . A five-year-old girl was killed by a stray bullet when attackers opened fire on an anti-government demonstration in eastern Trat province . The two youngsters in the capital were siblings , the children of a working-class family . The father , Thayakorn Yotubon , works as a personal assistant and driver -- he told me he spent every single night with his children and would never leave them alone . In one of the photographs at his children 's funeral , the little girl , nicknamed by her family as `` Cake , '' ( the brother was known as `` Kane '' ) is wearing a t-shirt that says `` I love Papa . '' `` She asked me to buy it for her to wear on Fathers ' Day , '' he told me , tears rolling down his face . Special day out . The day they were caught in the attack was a special day out because their aunt was visiting from out of town . She had brought Cake , Kane and her son out for a treat to the local shopping mall . They were waiting for a tuk-tuk -- a rickshaw taxi -- when a grenade was thrown into the crowds close to an anti-government rally outside the mall . Cake and Kane died from their injuries . Their cousin , who is 8-years old , is in critical condition in a hospital . We found his small , blood-drenched baseball cap at the scene . I have been covering the Thai unrest story from various protest sites , especially outside government buildings , but this time it was at the funeral of two young children . As we looked on and filmed , I questioned if we should be there -- if we should be filming their grief . But the family invited the cameras in . They did n't stop us and all spoke to my team . Despite my moment of doubt , I knew this was an important aspect of this whole story that needs to be shown to those involved . As Thayakorn so clearly put it : `` My kids were just children , sweet children . They were too young , they should not have done this to them ... They were just innocent children , they had nothing to do with this ( political issue ) . '' What 's behind the Thai unrest ? Their mother seated towards the back , was unable to bring herself to lift her head , wipe away her tears or talk to those sitting beside her . I watched as she was helped to her feet by family members , helping her take each shaky step towards her children 's bodies . `` These are not my children , '' she cried . `` They do n't look like that . '' Children 's bodies . Her children were laid out with their bodies bandaged and stitched together , their faces without expression , without the joy and happiness their father described to me . `` They were happy , innocent and sensitive kids , '' said Thayakorn . `` They loved to be around us -- their mum and dad all the time . They were sweet kids . '' This was a Buddhist ceremony . During the last rites , family members pour water through the person 's hands to symbolize the return of the body to the elements . But these hands were far too tiny , far too angelic , delicate and innocent to be there . I watched as the mother struggled to perform the ceremony . She could n't look at their faces -- she would n't look -- unable to accept or bear the burden of this loss . Even the Buddhist monk appeared lost for words as he looked on . I have been told that Buddhist funerals in Thailand are often somber events , with little emotion and outward shows of grief . But the passing of two innocent children in such circumstances was too much for all in attendance . Family members and friends were so distraught they could not utter words of condolence or comfort to ease the mother and father 's pain . And when the father came to perform the rituals -- he dropped to his knees , talking to his children . Crying out in disbelief : `` You were too young to die . '' In this corner of the capital , at least one family had paid too high a price for the political turmoil sweeping across the country .
