GAZA, Jan 12 (Reuters) - Leaders of several Palestinian militant groups told Hamas rulers in the Gaza Strip on Wednesday they would cease rocket fire at Israel in an effort to prevent any new Israeli offensive from being launched, officials said.

Two officials at a meeting convened by Hamas leaders told Reuters the factions had responded to warnings from Egypt that Israel, angry at increasing rocket attacks, may mount a campaign similar to one fought in 2009 that devastated much of the coastal territory.

Factions agreed to recommit to the national understanding to stop rocket firing, as long as Israel stops its air strikes and other attacks, one official said.
