"Israel has totally lost it," said Hamas leader Khaled Mashaal on Thursday evening in a reaction to Said Siam's assassination earlier that day.
According to Mashaal, the hit is proof of Israel being "unnerved", since "it couldn't cope with the Palestinian resistance activists in the Gaza Strip battlefield."
"Israel thought to finish the job by carrying out air strikes, but today is the 20th day [of the operation] and Israel has gained nothing. It didn't crush the resistance and didn't dictate the reality," he said.
"Israel has more fatalities than Hamas," added Mashaal.
