For the sake of a unbiased perspective - not easily available from the lowly ranked local paper - this is gleaned from the Economist's summary of the development at the Gaza strip:
The current violence was triggered by the murder of 3 Israeli teenagers, snatched on their way back from study at a yeshiva in an Israeli settlement in the West bank. That led to the the arrest of hundreds of Palestinians, including some prisoners recently released under an American sponsored scheme to boost peace talks with Abbas. In retaliation, and outraged at the murder of a young Palestinian, militants fired rockets into the heart of Israel. The Israel Defence Force responded with lethal force. A military spokeswoman told AFP that since the July 8 start of the military operation, over 2,000 rockets and mortar shells fired from Gaza hit Israel, with another 492 intercepted. A scenario that could have played out at the Little India enclave if the disgruntled foreign workers there had more effective projectiles at hand than trash cans and beer bottles.
In his facebook post, Lee said that while the Middle East is far away, Singaporeans still empathise with the pain and suffering of the Palestinian people, because of our common humanity. As if it's inhuman to empathise with the long suffering of our very own local born and bred.
