By Nidal al-Mughrabi and Steven Scheer CAIRO/JERUSALEM, Aug 2 (Reuters) - Israeli airstrikes continued in Gaza for a second straight day on Sunday, killing at least nine Palestinians, despite U.S. President Donald Trump's announcement of a breakthrough in efforts to implement last year's Gaza ceasefire agreement. Israeli Energy Minister Eli Cohen said on Sunday that there was no deal to halt attacks on Gaza and that he saw a need for Israel, which already controls 70% of the Strip, to take full control of it.
