The Israeli military says it struck 100 Hamas targets in the Gaza Strip overnight in response to rocket fire.

The army said early Friday that targets included an office complex in Gaza City, an underground complex that served as Hamas' main rocket-manufacturing site, and a center used for a Hamas drone program.

The airstrikes followed a rare rocket attack on the Israeli metropolis of Tel Aviv late Thursday. Israel says Hamas fired the rockets, though Hamas and a smaller militant group, Islamic Jihad, both denied involvement.

The fighting broke out amid Egyptian efforts to broker an expanded cease-fire deal between the bitter enemies, who last fought a war in 2014.

Several barrages of rocket fire continued during the night.
